The argument in one paragraph

This paper translates the analytical foundations of Parts I–III into an operational policy programme. International law and structural realism converge on the same conclusion: Russian military control of Crimea and Transnistria is the operational expression of a coherent occupation-by-proxy strategy applied across three cases — Transnistria (1990–92), Crimea (2014), and Donbas (2014–2022) — that is in sustained breach of the UN Charter, the Definition of Aggression, bilateral commitments Russia signed, OSCE undertakings Russia accepted, and binding ECHR effective-control jurisprudence. The Consolidated CBA establishes that combined deprivation releases €2.1–4.6 trillion of foregone European value across seven domains, with the regional dimension dominating the territorial by a 5–7× factor. The 30-actor coalition architecture identifies a viable Q1 “Rising Anchors” coalition led by NATO HQ, the EU Commission, the UK and France, anchored in Eastern Flank states and exposed on a single material variable: the United States position in Q3 “Eroding Allies”. The Cost of Coordinated Action across the four sub-variants probability-weights to €1,408 billion against an Expected Net Strategic Value (NSV) of ~€1,800 billion: the programme pays for itself by 1.30× at central view and 2.65× under marginal attribution, with sign-invariance across all sensitivity classes examined. CDW.2 institutional-partial dominates every column of the NSV matrix; CDW.1+CDW.2 is the operational target.

1. The Dual Foundation: Legal and Realist Anchors

1.1 The legal foundation: occupation by proxy across three cases

Russian control of Crimea and Transnistria is not a legally ambiguous frozen-conflict situation requiring novel doctrine. It is the sustained operational expression of a documented Russian playbook — what the analytical literature has termed occupation by proxy — applied across three cases at different scales and speeds, and engaging multiple overlapping bodies of public international law. The legal architecture is layered: at its base, jus cogens norms on the use of force codified in the Charter of the United Nations (Article 2(4)); above that, bilateral instruments Russia itself negotiated and breached; above that, OSCE undertakings Russia accepted and never executed; and above that, binding ECHR jurisprudence establishing Russian state responsibility for occupied territory as a matter of European law.

The same operational signature manifests in all three cases: covert or denied military insertion (the Soviet/CIS 14th Army's combat participation against Moldovan forces January–July 1992; Russian “little green men” in Crimea February 2014; irregular Russian forces inserted into Donbas from spring 2014); staged self-determination events providing thin legal cover (the 1990 Transnistrian declarations and unrecognised “referendum”^[1]; the 16 March 2014 Crimea “referendum” under occupation; the May 2014 and September 2022 Donbas referendums); and installation of parallel proxy administration under continuous external command and finance. This pattern engages the Definition of Aggression (UNGA Resolution 3314 (XXIX), 14 December 1974) simultaneously at branches 3(a), 3(e), 3(f), and 3(g). Article 5 establishes that no consideration whatever can serve as justification for aggression and that aggression is a crime giving rise to international responsibility.

Transnistria: 30+ years of breached withdrawal architecture

Transnistria is the prototype, and its legal architecture rests primarily on Russian commitments Russia itself undertook and then abandoned. President Yeltsin publicly pledged the withdrawal of the 14th Army on 21 May 1992; the 1994 Russia–Moldova bilateral agreement set a 3-year withdrawal timeline; the 1999 OSCE Istanbul Summit Declaration committed Russia to complete withdrawal by end-2002; the Adapted CFE Treaty made Russian withdrawal an Istanbul Commitment and prerequisite for NATO ratification; UNGA Resolution 72/282 (22 June 2018) called for “complete and unconditional withdrawal of foreign military forces from Moldova”. None has been executed. The Operational Group of Russian Forces (~1,500–2,000) and the Transnistrian Armed Formations (~15,000, with declared mobilisation potential of 50,000) constitute a 17,000–21,000 force without supply line to Russia, sustained as the southern node of Russia's distributed pressure architecture; the Cobasna depot continues to hold strategic ammunition reserves. The Parliamentary Assembly of the Council of Europe, in PACE Resolution 15477, expressly qualified the situation as the act of military aggression against the Republic of Moldova and respectively the occupation of its Transnistrian region. The European Court of Human Rights converts these factual findings into binding state responsibility. Ilașcu and Others v. Moldova and Russia (8 July 2004) established the Russian Federation's direct involvement in creation and active fight against Moldova by military, financial, economic, political, diplomatic and other means. As a matter of binding European law, Russia exercises effective control over Transnistria and bears state responsibility for the human rights situation on the territory. This converts contested attribution into a settled judicial finding.

Crimea (2014) and Donbas (2014–2022): the same playbook accelerated

The 2014 Russian operations against Ukraine applied the Transnistria framework with substantially compressed timelines and far broader legal violations. The legal architecture engaged is overdetermined: the Helsinki Final Act (1975) on the inviolability of frontiers; the Charter of Paris (1990); the 1991 Alma-Ata Declaration through which Russia recognised the borders of the Soviet successor republics; the 1994 Budapest Memorandum on Security Assurances; the 1997 Russia–Ukraine Friendship Treaty; and the 1997 Black Sea Fleet Status of Forces Agreement. The multilateral response includes UNGA Resolution 68/262 (March 2014, 100–11), ES-11/1 (March 2022, 141–5), ES-11/4 (October 2022), the ICJ Ukraine v. Russian Federation case, the ICC arrest warrants of March 2023. Targeted sanctions architectures — EU Council Regulation 692/2014 and US Executive Order 13685 — operationalise the non-recognition framework. The Crimea case strengthens Transnistria's; the Transnistria ECHR jurisprudence strengthens Crimea's.

1.2 The realist foundation: three layers converging on a 2032–2035 inflection

Where the legal foundation establishes that deprivation is lawful, the realist foundation establishes that it is structurally consistent and operationally tractable. The realist foundation is layered across three analytical strata. Part I establishes the historical baseline: across 2,500 years and sixteen periods, the developmental–military binary is absolute, not gradual; military establishment is always a deliberate imperial choice; the speed asymmetry is catastrophic (weeks to destroy, 111–419 years to recover); the two territories form a single geographic system; alliance embedding is the structural prerequisite for survival (the Polish-Lithuanian Commonwealth (PLC) sustained left-bank development for ~300 years); and no garrison economy in 2,500 years has ever organically transformed into a developmental economy. Waiting for Transnistria or occupied Crimea to self-reform is therefore historically unprecedented and analytically unsupported.

Part III's 120-factor architecture quantifies what Part II implies for the present horizon. Five trajectories converge on the 2032–2035 inflection. The demographic clock: the Russian male population aged 20–34 declines from 14.25M (2020) to 11.23M (2030) — a 21% reduction in the military-age recruiting pool — while the Crimean garrison and other forward positions consume 2–3% of the shrinking pool annually. The defence-industrial differential: NATO at $1.506T versus Russian $140B, with the proposed 2%→5% NATO trajectory potentially adding cumulative European defence investment on the order of $15T through 2050. The transparent battlefield: the 2,000:1 detect-to-engage compression makes garrison sustainment progressively impossible regardless of static fortification. The macroeconomic base: Russian share of world GDP declines from 1.9% (2025) toward 1.1% (2075); Russia leads in 0 of 12 frontier technology categories; Northern Corridor energy transit collapses by ~90%. The Sino-Russian asymmetric coupling: China slows Russian industrial depletion by ~25–30% but cannot reverse direction.

Figure 1.1. The Converged Anchor — Combined Deprivation Window (CDW) in the Part III four-scenario architecture. Left panel: baseline scenario probabilities (CDW ~20%, PS ~35%, LO ~17%, SD ~28%) on Meta-Axis A (Russia weakening / consolidating) and Meta-Axis B (West coherent / fragmenting). Right panel: probability shift achievable under the three Western-controllable policy levers — sustaining Western coherence, securing Ukrainian post-war population at 30M+, and preserving Moldovan demographic viability. CDW probability is plausibly movable from ~20% baseline toward 28–32% by 2030 under sustained, coordinated Western action; LO/SD compress correspondingly. Source: Part III scenario architecture; Master Ranked Table v3.1.

Part III populates the four scenarios across two meta-axes. Meta-Axis A captures Russia's trajectory — weakening through state stress, succession, or fracture (P(A+) = 37%) versus consolidating through continuity (P(A−) = 63%). Meta-Axis B captures Western coherence and Ukrainian viability as a combined dimension (P(B+) = 55% versus P(B−) = 45%). CDW — Russia weakening + West coherent + UA viable — sits at ~20% baseline; PS (Pressure Stalemate) at ~35%; LO (Lost Opportunity) at ~17%; SD (Strategic Defeat) at ~28%. CDW is structurally a minority outcome at ~20% against the combined ~80% probability of failure variants — but the architecture is not deterministic. Three Western-controllable policy levers shift scenario probability significantly: (1) sustaining Western coherence — raising P(B+) from 55% toward 65–70% — directly compresses LO and SD probability mass; (2) securing Ukrainian post-war population at 30M+, the master variable that most cleanly separates CDW + PS from LO + SD; (3) preserving Moldovan demographic viability to prevent the partial-delivery scenario where the architecture holds but Moldova erodes below the absorption threshold. Realistic ceilings on these levers, integrated across the project corpus, suggest CDW probability can plausibly be moved from ~20% baseline toward 28–32% by 2030 under sustained, coordinated Western action.

1.3 The converged anchor

Sections 1.1 and 1.2 converge on the same operational conclusion through independent reasoning. Russian military control is both legally unfounded and structurally unsustainable, and combined deprivation is both lawful recovery and structurally consistent with the empirical record. The convergence is not coincidental: the legal instruments and the structural pattern reflect the same underlying reality — that imperial military control of geographically complementary trade-node territory is anomalous, contested, and historically transient. The occupation-by-proxy framework Russia applied first in Transnistria and accelerated in Crimea and Donbas is precisely the asymmetric, deniable modality Part II identifies as Russia's narrowing strategic toolkit. This converged anchor pre-empts three categories of incrementalist objection: that “realism requires accepting facts on the ground” — but the structural facts are themselves changing on every measurable vector; that “international law is too weak to compel state behaviour” — but the legal architecture supplies the conditional structure for the institutional pathway (Chapter 31 EU accession benchmarks, ECHR effective-control jurisprudence, sanctions enforcement, ICC and ICJ proceedings) without requiring direct enforcement; and that “deprivation is destabilising or revisionist” — but both deprivations are recovery actions for obligations Russia itself accepted and breached, not novel territorial demands. The legitimacy reservoir is the conditional structure on which the institutional pathway functions, the cost-benefit case credibly answers the audience, the actor coalition can be mobilised, and the cost of action is justified.

2. The Cost-Benefit Case: €2.1–4.6 trillion of foregone European value^[2]

2.1 The three failure scenarios: €2.1bn, €3.2bn, €4.6bn

The analysis is based on the approach of the cost of inaction towards CDW scenbario. The aggregate cost is benchmarked against three failure scenarios drawn from the Part III architecture. Patient Pressure (PS.1): Russia weakens slowly; combined deprivation is deferred to 2035–2040 rather than 2025–2035 — €2,132 bn foregone, equivalent to 12.5% of EU 2025 GDP. Limited Options (LO.1): a Turkey-led Black Sea arrangement produces partial, fragmented deprivation — €3,240 bn (19.1% EU GDP). Strategic Decoupling (SD.1): Cold War 2.0 with combined deprivation blocked indefinitely and civilisational fragmentation — €4,608 bn (27.1% EU GDP). The 2.2× ratio between best and worst failure mode shows that which failure arrives matters by trillions of euros. All figures NPV in real EUR, base year 2025, declining-STPR discount schedule per HM Treasury Green Book convention.

Table 2.1. The three failure scenarios against which combined deprivation is benchmarked. The 2.2× ratio between best and worst failure mode shows that which failure arrives matters by trillions of euros.

2.2 The regional dimension dominates the territorial by 5–7×

The aggregate cost has two components that do not double-count. The territorial component captures effects inside Crimea and Transnistria — GDP convergence toward EU candidate-state trajectories, sectoral reactivation (Sevastopol and Kerch ports, Rîbnița metallurgy, Cuciurgan electricity, the Bender–Tiraspol industrial corridor), and resolution of contested property rights. The territorial figure ranges from €373 bn (PS.1) to €577 bn (SD.1). The regional component captures effects across the wider Eastern Europe and Black Sea space when Russian military presence is removed from both territories. Regional ranges from €1,759 bn (PS.1) to €4,031 bn (SD.1) — between 4.7× and 7.0× the territorial figure. This is the most operationally important finding. The case for combined deprivation does not rest primarily on the value of returning Crimea or Transnistria to integrated development — that is the necessary mechanism, but it is the smaller of the two value pools. The case rests on what their continued occupation costs the wider region. Policy communication that leads with territorial reintegration understates the proposition by an order of magnitude.

Figure 2.1. The €2.1–4.6 trillion question. Left panel: aggregate foregone European value across the three failure scenarios, decomposed into territorial (inside Crimea + Td) and regional (Eastern Europe / Black Sea) components. The regional-to-territorial ratio rises from 4.7× under PS.1 to 7.0× under SD.1. Right panel: the seven-domain regional suppression premium (aggregate ~€1,810 bn pre-loop-multiplier, pre-precautionary discount). Approximately €350 bn of regional value activates ONLY under combined deprivation — three-node reconstitution, seven-domain feedback loop, and the integrated Black Sea renewable basin produce zero value under any partial alternative. Source: Consolidated CBA Crimea + Td (December 2025); Strategic Deprivation Series Papers 1–6.

2.3 The seven-domain feedback loop and the €350bn combined-only premium

The regional component decomposes across seven domains that interact through compounding feedback loops: technology(€480 bn — frontline-state innovation premium, sovereignty stack, civilisational coupling); energy (€420 bn — 100–200 GW Black Sea offshore wind potential, gas hubs, integrated renewable basin); corridor (€350 bn — Middle Corridor capacity scaling from 4.5 to 40–60 Mt/year, Three Seas connectivity); food/agriculture (€230 bn — Black Sea breadbasket integrity, chernozem, three-node agriculture); security/defence (€130 bn — forward-defence procurement avoidance, ISR integration); demographic (€110 bn — return migration, fertility recovery, threshold-coded stabilisation); and strategic alignment (€90 bn — EU/NATO institutional coherence, sanctions architecture sustainability). Aggregate €1,810 bn pre-loop-multiplier, pre-precautionary discount. Each domain carries a feedback loop: gains in one accelerate gains in the others.

“Combined” matters because three of the largest benefit categories — three-node reconstitution of the historical Kaffa + Tighina + PLC complementarity (Part I), the seven-domain feedback loop, and the integrated Black Sea renewable basin — produce zero value under any partial alternative. They are not diminished under half-measures; they are absent. Their aggregate worth is approximately €350 billion that no partial deprivation can recover. Four routes to combined deprivation are possible — kinetic, institutional, single-event rupture, and chaotic — but all four release substantially the same value pool (within ±10%). The route matters less than the fact.

2.4 Territorial and Regional Benefits

The aggregate Cost of Non-Combined-Deprivation (CoNCD) is the sum of two non-overlapping cost streams: the territorial component — value foregone inside Crimea and Transnistria themselves through continued military occupation - and the regional component — value foregone across the wider Eastern European and Black Sea space through the suppression effects radiating from those territories. The decomposition is constructed to be additive without double-counting: territorial CBAs price reactivated assets (Sevastopol and Kerch port throughput, sectoral reactivation, Bender–Tiraspol industrial corridor restitution, contested-property resolution) while the regional CBA prices the seven external suppression domains (technology, energy, corridor, food/agriculture, security/defence, demographic, strategic alignment) that operate through but not inside the territories. Disaggregating the joint territorial component shows that Crimea contributes approximately 73% (€272–421 bn across the three failure scenarios) and Transnistria approximately 27% (€101–156 bn) — a ratio that reflects the sevenfold population differential, the higher capital intensity of Crimean infrastructure assets, and the larger Black Sea coastline economic frontage.

Aggregate Cost of Non-Combined-Deprivation with separated Crimea and Transnistria territorial CBAs. Crimea contributes ~73% of the joint territorial component; Transnistria ~27%. The €2.1–4.6 tn central range across PS.1–SD.1, and the 4.7×–7.0× regional-to-territorial ratio, are robust to the parameter uncertainty shown in the sensitivity bracket. All figures NPV in real EUR, base year 2025, declining-STPR discount schedule per HM Treasury Green Book convention. Source: §B.1 (Crimea and Transnistria territorial CBAs); §C.4 (regional CBA, seven-domain decomposition); macro-projection base from Goldman Sachs Path to 2075, PwC World in 2050, OECD Long-Run Economic Scenarios.

Three findings carry the analytical weight. First, the regional-to-territorial ratio rises monotonically with the severity of the failure scenario — from 4.7× under Patient Pressure to 5.9× under Limited Options to 7.0× under Strategic Decoupling. As the failure mode hardens, the suppression damage propagates outward faster than it accumulates inside the two territories themselves; Cold-War-2.0 conditions impose a regional integration tax that is more than twenty times the foregone Transnistrian territorial value alone. Second, the aggregate CoNCD scales from 12.5% of EU 2025 GDP under PS.1 to 27.1% under SD.1 — the worst-case failure mode foregoes more than a quarter of the Union's current annual output over the projection horizon, and the central range exceeds annual NATO defence spend by 125–270%. The cost of inaction is larger, by two orders of magnitude, than the entire SAFE €150 bn defence-industrial mobilisation that the Coalition of the Willing is currently contesting. Third, the sensitivity bracket preserves both the central range and the dominance ranking — the lower bound under PS.1 (€1,580 bn) still exceeds 9% of EU GDP; the upper bound under SD.1 (€6,020 bn) approaches 35%. No reasonable parameter combination collapses the regional-dominance finding or moves the aggregate CoNCD below the threshold at which combined deprivation becomes a first-order policy priority. The robustness of the headline number to parameter perturbation is the decisive analytical feature: the case for combined deprivation does not depend on the discount rate, the population trajectory, or the corridor capacity assumption — it depends only on the structure of the suppression mechanism, which is invariant across the sensitivity space.

Aggregating the Crimea and Transnistria territorial cost-benefit calculations and the Black-Sea-Eastern-European regional cost-benefit calculation produces the headline Cost of Non-Combined-Deprivation. The central range is €2.1–4.6 trillion NPV 2025–2050 across the three failure scenarios. The regional component dominates the territorial component by a factor of 4.7× under PS.1 rising to 7.0× under SD.1 — the case for combined deprivation rests primarily on the wider regional value pool, not on the value of the two territories themselves.

2.5 Distributional Incidence Analysis by Actor and Country

This decomposition allocates the PS.1 aggregate Cost of Non-Combined-Deprivation across twelve actor categories — eleven Western coalition cost-bearers plus one adversary capture row — over the same NPV 2025–2050 horizon used in §D.1.3 (real EUR, base year 2025, declining-STPR discount schedule). The Western total of €2,078 bn monetised plus adversary capture of €130 bnyields €2,208 bn gross foregone value, reconciling to the §D.1 PS.1 central estimate of €2,132 bn within ~3.4% methodological tolerance — the reconciliation is itself the validation that horizon and discount conventions match. Cost is distributed diffusely: no single actor category exceeds 19% of the total — the structural property that makes the coalition tractable.

Four structural tiers. The cost surface decomposes into four operationally distinct burden-bearing tiers. The EU collective tier (institutional + cohesion + non-cohesion) absorbs €910 bn or 44% of the Western total — split €355 bn cohesion / €415 bn non-cohesion, with the €140 bn institutional layer (European Commission, EIB, ECB exposure, Ukraine Facility, EPF, MFA+) sitting on top. The frontline-state tier (Ukraine + Moldova) absorbs €435 bn or 21% — small in nominal economic mass but disproportionate in burden density, with risk-premium intensity ratios of 26% (Ukraine) and 28% (Moldova) against 5–10% for all other monetised categories. The private-sector and sub-state tier (energy IOCs €155 bn + corridor/logistics €115 bn + Crimean/Td populations €113 bn) absorbs €383 bn or 18% — a constituency of corporate, regional, and population-level cost-bearers that cannot be captured through a single political authorisation channel. The United States tiercarries €105 bn or 5% — modest in absolute terms but functionally critical given its swing-actor role in the coalition map.

Table. Distributional incidence of the PS.1 Cost of Non-Combined-Deprivation across twelve actor categories. All figures NPV 2025–2050 in real EUR, base year 2025, declining-STPR discount schedule (HM Treasury Green Book) — identical horizon and methodology to §D.1.3 Table D.1.1. PS.1 Western total ≈ €2,078 bn monetised + adversary capture €130 bn = €2,208 bn gross (reconciles to §D.1 PS.1 €2,132 bn within methodological tolerance). Adversary row negative because value is captured (transferred to Russia, China, Iran, Belarus regime), not destroyed. Strategic-tag column shaded by priority weight: Critical = objects of CDW; High = coalition leads and sub-state beneficiaries; Moderate = contributors and swing exposures; Adversarial = Anti-CDW pole. Source: §D.1 aggregate; §C.4 seven-domain regional decomposition; Strategy_Coalition.docx 30-actor mapping.

Where kinetic exposure concentrates. The risk-premium column reveals the structural location of war-driven cost loading. Ukraine carries €90 bn — 34% of total Western risk-premium loading — reflecting the active conflict zone, post-war reconstruction uncertainty, and continuing capital-account mark-up. Moldova carries €25 bn at 28% intensity ratio, exceeding even Ukraine's 26% intensity — the smaller, less-resilient frontline state actually absorbs a higher proportion of its total loss through risk-pricing channels than through direct economic damage. Black Sea littoral (€18 bn) and Three Seas eastern flank (€15 bn) form the second-tier kinetic-exposure ring. The remaining seven categories share €115 bn risk-premium across diffuse, manageable channels. The composition matters: frontline-state risk-premium is compressible through Western coordination (security guarantees, capital-account backstops, EU absorption) — exactly the mechanism that combined deprivation operationalises. The €115 bn Western-collective risk-premium is the price of the coordination itself.

EU cohesion vs non-cohesion: structural, not random. The €355 bn cohesion / €415 bn non-cohesion split conceals an overlap pattern. Cohesion states (Romania, Bulgaria, Poland, Czechia, Slovakia, the Baltic three, Croatia, Slovenia) appear simultaneously in the Three Seas eastern flank row (€129 bn) and partly in Black Sea littoral (€116 bn) — frontline cohesion countries therefore bear concentrated indirect-macro and risk-premium loadings stacked across three categorical dimensions. Non-cohesion states (Germany, France, Italy, Spain, Netherlands, Belgium, Nordics, Austria, Ireland) absorb the larger absolute share through direct economic channels (€220 bn) — capital exposure, manufacturing supply chains, energy import dependencies. The institutional layer (€85 bn direct fiscal) is the political instrument through which Western cost is laundered into a single authorisation channel — the SAFE €150 bn precedent shows the capacity exists.

The adversary capture row is the highest-leverage line in the table. Reported with negative sign to indicate that value is transferred not destroyed, €130 bn flows from the Western system to Russia (state + Rosneft / Gazprom / VTB), China (BRI offsets and critical-raw-materials leverage), Iran (UAV/missile supply revenue and sanctions-arbitrage rents), and the Belarus regime. This represents 6.1% of gross foregone value but greater than 100% of marginal welfare effect — every euro captured strengthens the very suppression mechanism that produces the underlying €2,078 bn loss, creating a positive feedback in adversary capability and a corresponding negative feedback in Western strategic optionality. Combined deprivation is the structural mechanism that interrupts this transfer; the negative-sign accounting convention obscures rather than reveals the analytical importance of this row. From a policy-economy view, eliminating the €130 bn capture is the single instrument that simultaneously reduces all eleven other rows.

Strategic tags map onto the §3 functional-role architecture. The Critical tier (Ukraine + Moldova) is the §3.2 Objects of CDW — territories whose recovery the deprivation programme exists to enable. The High tier (EU institutional + USA + Crimean/Td populations) corresponds to the coalition-leads category and the sub-state beneficiary cluster — actors whose strategic alignment must be secured for the programme to operate. The Moderate tier corresponds to second-ring contributors and swing-actor exposures — the political mass that the Q1 "Rising Anchors" coalition has to assemble. The Adversarial tier is the Q4 declining-but-active Anti-CDW pole. The qualitative-tag distribution recovers the §3 coalition map directly from the cost-incidence data — the two analytical layers are mutually consistent.

2.6 Five findings

•   Combined deprivation is qualitatively, not just quantitatively, better. Three of the largest benefit categories are non-recoverable by any half-measure (~€350 bn).

• The institutional configuration beats the kinetic one. Across three independent robustness tests — vulnerability stress-testing, ranking stability, and worst-case regret minimisation — the institutional-partial configuration (CDW.2) outperforms kinetic-prepared and rupture-driven alternatives. Institutional substrate beats military posture.

•   The binding constraint is institutional, not military. Three institutional levers — sustained Western coherence, Ukrainian post-war population at 30 million or above, Moldovan demographic viability — together control €500–1,000 bn of the cross-scenario differential. Each is substantially within Western political control.

•   The regional dimension dominates the territorial by 5–7×. Lead policy communication with the regional figure (€1.76–4.03 tn), not the territorial figure (€373–577 bn). Territorial reintegration is the mechanism; regional release is the value.

•   The 2025–2035 window preserves €75 bn of optionality. Even if combined deprivation is deferred to 2035–2040, the institutional investments made in the next decade preserve roughly €75 bn of optionality. Allow any of these to degrade and the optionality collapses.

3. The Actor Architecture: a 30-actor Coalition Map^[3]

3.1 The four operational quadrants

Figure 3.1 places the 30 actors in a two-dimensional plane defined by alignment direction (D7) on the horizontal axis and trajectory (D8) on the vertical axis. Bubble size encodes raw capability — the sum D1 + D2 + D3 + D4-magnitude + D5-defensive + D5-offensive + D6 — rather than the Aggregate S score, which would double-count alignment. Bubble colour shows the gate result (green Pro-CDW reliable, amber Pro-CDW with material constraint, grey Neutral or transactional, red Anti-CDW). Marker shape distinguishes category (circles for sovereign states, squares for institutions, pentagon for the Cat 1* compromised hegemon, hexagon for the Cat A peer adversary, diamonds for Cat 5 external adversaries, triangles for Cat 6/6* sub-state and frontline-victim actors).

Figure 3.1. The 30-Actor CDW Coalition Map: capability × alignment × trajectory. Q1 (top-right) holds the rising-anchor coalition: NATO HQ and EU Commission as institutional apex; Cat 1 European apex (UK, France); Cat 2 Western anchors (Germany, Italy, Canada); the Cat 3 frontline reliable cluster (Sweden, Poland, Netherlands, Finland, Lithuania, Romania, Estonia, Latvia, Greece); and the two Cat 6* frontline-victim Pro-CDW objects (Ukraine, Moldova). Q3 (bottom-right) holds the United States at Q-net = −0.75 (Q-policy −1.5 / Q-institutional +1.0) under the v3.1 dual-track methodology, plus OSCE. Q4 (bottom-left) holds Russia, Belarus, Iran (stable not declining), the Cat 6 territorial nodes Crimea and Transnistria, and the Hungary/Slovakia fellow-traveller cluster. Q2 holds China alone.

The deprivation thesis is visible as the diagonal: pull Q4 (Russia, Belarus, Crimea, Transnistria) further into ↘ while protecting Q1 (the rising-anchor cluster) in ↗, with Q2 (China) contained and Q3 (US Q-policy) hedged so that the United States does not slide further down-left into Q4. The 2026 H2 – 2027 H1 critical window concentrates five inflection events (US midterm 3 November 2026, Sachsen-Anhalt LTW September 2026, EU Cluster 1 sequence, Bulgarian presidential succession January 2027, France 2027 presidential) — coalition execution discipline across this 18-month period determines whether the deprivation thesis advances toward Maximum Deprivation (22% probability ceiling) or downshifts into Bifurcated Progress (18% modal outcome).

3.2 Functional roles: leads, contributors, swing actors, vetogates, objects

Within-category aggregation gives the structural ranking; functional roles describe what each actor does in the CDW operational task. Six functional categories cover the 30-actor population.

Table 3.1. Functional role architecture across the 30-actor population. Coalition leads + second-ring contributors = 14 Pro-CDW actors carrying the operational delivery; swing actors (US + Türkiye) determine sub-variant feasibility; vetogates determine institutional pathway viability; objects of CDW are the operational deliverable; the Anti-CDW pole is the system being deprived.

3.3 The strategic axis and the 2026 H2 – 2027 H1 critical window

The deprivation thesis is visible as the diagonal in Figure 3.1: pull Q4 (Russia, Belarus, Crimea, Transnistria) further into ↘ through DEPRIVE & ATTRITION while protecting Q1 (the rising-anchor cluster) in ↗ through PROTECT & DEEPEN, with Q2 (China) contained through CONTAIN & DECOUPLE and Q3 (US Q-policy) hedged through STABILISE & HEDGE so that the United States does not slide further down-left into Q4. The 2026 H2 – 2027 H1 critical window concentrates five inflection events: US midterm 3 November 2026; Sachsen-Anhalt LTW September 2026; EU Cluster 1 enlargement sequence; Bulgarian presidential succession January 2027; French 2027 presidential. Coalition execution discipline across this 18-month period determines whether the deprivation thesis advances toward Maximum Deprivation or downshifts into Bifurcated Progress.

Coalition action sequenced against the trigger calendar separates into three windows: critical 2026 H2 – 2027 H1 (18 months); stabilisation 2027 H2 – 2028 (18 months); consolidation 2029 – 2030 (24 months). Figure 6 shows the workstream timeline; Sections 2.1–2.3 specify the action architecture per window.

Six workstreams at intensity 0.75. Two time-critical interventions: pre-US-midterm sanctions closure (Aug–Oct 2026); post-US-midterm exploitation window (Nov 2026 – Feb 2027). Failure to execute this window at this intensity downshifts the scenario distribution from Maximum Deprivation 22% / Bifurcated Progress 18% toward Bifurcated Progress / Extended Pressure / Defensive Holding cluster.

The Q1strategy is PROTECT & DEEPEN: lock anchors via NATO 5% trajectory and EU SAFE €150 bn execution; front-load Article 215 sanctions packages 21–22 before Hungary takes the EU Council Presidency in Q1 2027; expand the Coalition of the Willing for Ukraine and Moldova security guarantees; bind Td-deprivation conditionality to Cluster 1. The Q2 strategy is CONTAIN & DECOUPLE: accelerate the Critical Raw Materials Act and 17 strategic projects; sustain US-NL-JP semiconductor export-control coordination; deepen Chinese-entity sanctions enforcement across EU packages 13–22; calibrate the Anti-Coercion Instrument. The Q3 strategy is STABILISE and HEDGE: run parallel-channel diplomacy through Pentagon, Treasury OFAC, Congress, SCOTUS and state-level interlocutors; rely on bilateral US Defense Cooperation Agreements as institutional ballast; pre-position the European-Pillar Pivot fallback (EU Defence Union + UK–France Northwood architecture); manage 2026 midterm and 2028 succession as inflection events. The Q4 strategy is DEPRIVE & ATTRITION: execute combined Cat 6 deprivation through DCFTA enforceable conditionality (Transnistria) and sustained Ukrainian deep-strike (Crimea); hold the sanctions architecture to keep Russia on a declining trajectory through 2030; deploy NATO Forward Defence brigade architecture against Belarusian extended-operational-space; pre-position post-Lukashenko and post-Putin succession 2028–2032 contingencies; deny Iranian kinetic-supply scaling via E3 + JCPOA snapback enforcement.

Each of the institutional pathways as per the chart below carries distinct anchor-and-co-leader patterns, distinct vetogate exposure, and distinct workstream contributions. Figure shows the pathway × workstream venue map.

Figure  Pathway × workstream action venue map (◆ anchor; PRI primary; sec secondary)

NATO HQ (S=41.5): Workstream contributions: CDW.1 anchor; CDW.4 primary venue (STRATCOM CoE Riga + CCDCOE Tallinn); CDW.2 active sponsor (open-door + MAP); CDW.3 secondary (institutional coordination role). Vetogate exposure: Türkiye (precedent: Sweden accession 2022–24); Hungary (declaratory disruption); US under Q-policy (structural participant via Pentagon + Aegis Ashore + Forward Defence brigades; bilateral DCAs sustain operational continuity).

EU Commission (S=35.0): Workstream contributions: CDW.2 anchor (enlargement architecture); CDW.3 anchor (sanctions, frozen-asset, trade coercion); CDW.1 secondary (industrial-financing complement to NATO HQ + member-state forces); CDW.4 active contributor.

EU Commission: The QMV pathway operates in parallel to unanimity where treaty allows: most internal-market and trade-policy decisions; Anti-Coercion Instrument (Reg. 2023/2675) implementing acts; CRMA (Reg. 2024/1252) implementing acts; CBAM (Reg. 2023/956) implementing acts; EU Chips Act (Reg. 2023/1781). Türkiye outside (non-member). Workstream contributions: CDW.2 primary; CDW.3 anchor for implementing-act layer; CDW.1 + CDW.4 secondary.

Bucharest9: Poland, Romania. Participants: Lithuania, Latvia, Estonia, Slovakia (by reference), Czech Republic, Hungary (with reservations), Bulgaria. Workstream contributions: CDW.1 primary venue (Eastern-Flank pre-alignment ahead of NATO consensus); CDW.4 secondary. Vetogate exposure: minimal within-format (Hungary participates with reservations).

NB8 / JEF: Sweden, Finland, UK. JEF (Joint Expeditionary Force) is a 10-nation framework UK-led; the 2022 Tallinn Summit operationalised rapid response without 32-state NATO consensus requirement. Workstream contributions: CDW.1 primary venue (Nordic-Baltic complementarity to B9 Eastern-Flank); CDW.4 secondary. Vetogate exposure: minimal — highest consensus density in the alliance.

Coalition of the Willing / Lancaster House: UK, France. The 39-nation Paris Declaration of Intent 6 January 2026 establishes MNF-U; Paris Coalition Operational HQ. UK-France Nuclear Steering Group Paris 10 December 2025 deepens the Northwood Declaration (10 July 2025) bilateral nuclear coordination. Macron 5 March 2025 strategic dialogue announcement initiated EU-collective-defence nuclear-deterrence dialogue (Poland identified as key partner). Workstream contributions: CDW.1 anchor for post-settlement security guarantees; CDW.2 + CDW.3 secondary. Vetogate exposure: bypasses NATO consensus where speed-of-action required; bypasses EU unanimity for CoW-internal decisions.

Five Eyes: United States, United Kingdom. Other participants: Canada, Australia (not in 30-actor population), New Zealand. Workstream contributions: CDW.4 anchor (intelligence-cooperation tier-1; counter-Russian-FIMI doctrine production); CDW.1 secondary (operational intelligence support). Vetogate exposure: US Q-policy compromised-hegemon flag affects but does not currently sever Five Eyes operational continuity.

Weimar+: Germany, France, Poland. Weimar+ observers: Italy, Spain, Netherlands; UK on topic-specific basis. Workstream contributions: CDW.1 secondary; CDW.2 secondary; CDW.3 secondary (defence-industrial coordination + European Pillar deepening). Vetogate exposure: minimal within-format (no veto-bearing actor).

3SI: Poland. Co-leader: Romania. Participants: Estonia, Latvia, Lithuania, Hungary, Czech Republic, Slovakia, Slovenia, Croatia, Austria, Bulgaria. The US has been the main external sponsor. Workstream contributions: CDW.2 secondary; CDW.3 secondary (energy + infrastructure North-South corridor). Vetogate exposure: minimal (parallel to EU institutional pathways).

4. The Cost of Action and Net Strategic Value^[4]

4.1 The Cost of Coordinated Action: six programme components

The Cost of Coordinated Action (CoCA) decomposes across six programme components mapped to specific EU and bilateral instruments. (A) Defence-industrial mobilisation (€284 bn): SAFE €150 bn, EDF, EDIP/ASAP/EDIRPA, EPF, EUMAM Ukraine, DIANA + NATO Innovation Fund — co-led by France + UK + Poland + Germany. (B) Frontline-state security (€450 bn — the largest component): Ukraine bilateral assistance €285 bn G7+, Ukraine Facility €50 bn, Moldova Defence Modernisation, eFP Eastern Flank deepening — led by UDCG (UK–Germany co-chair). (C) Enlargement architecture (€108 bn): Reform and Growth Facility €18.9 bn, MFF 2028–34 follow-on €60–90 bn, Chapter 31 conditionality activation — led by EU Commission + Romania + Germany. (D) Sanctions architecture (€85 bn): EU sanctions packages 19th–22nd, UK OTSI, US OFAC parallel, shadow-fleet enforcement. (E) Civil protection and resilience (€278 bn): Counter-FIMI, critical-minerals diversification, energy redundancy (Vertical Gas Corridor, BSSC), refugee absorption, cyber defence. (F) Reconstruction and reintegration (€50 bn): Transnistrian institutional absorption €30–40 bn, Ukraine reconstruction within scope €10–15 bn — Crimea deferred under CDW.2.

Figure 4.1. Cost of action and Net Strategic Value. Left panel: the 4×3 NSV matrix at central programme-instrument view. All twelve cells are positive (range +€595 bn CDW.4 vs PS.1 to +€3,295 bn CDW.2 vs SD.1). CDW.2 institutional-partial dominates every column (highest NSV against PS.1, LO.1 and SD.1; highest E[NSV]/CoCA ratio at 1.47×). The SD.1 column (red dashed border) produces 62% of aggregate Expected NSV — the principal political-economy case for CDW is tail-risk avoidance against Cold War 2.0 outcomes. Right panel: CoCA breakdown by the six programme components; Total CoCA (CDW.2 central) = €1,305 bn, probability-weighted E[CoCA] = €1,408 bn. Source: Part IV §4 (CoCA distributional architecture); Part IV §5 (sub-variant strategy ex-ante); Part IV §6 (Net Strategic Value matrix).

Distributional concentration matters. The twelve actor categories range from large spenders (EU non-cohesion member states ~€340 bn, EU Commission institutional ~€305 bn, UK ~€185 bn) to small but politically-significant actors (Moldova as recipient with growing absorption capacity, Ukraine as the operational regional anchor). Five-actor concentration — EU non-cohesion member states, EU institutional, USA (€63 bn under Trump-2.0 base case rising to €100–130 bn under midterm Democratic House recapture), UK, and Ukraine + Moldova absorption — together carry ~70% of the burden. This is what makes the coalition feasible. Large coalitions with diffuse cost-bearing tend to fail political-economy tests; concentrated burden-bearers can be assembled politically. The principal alliance-fracture risks (Hungarian/Slovak/Cypriot Council vetoes) operate on contestable budget items at the EU institutional layer, where qualified-majority routing and bilateral bypass channels can absorb residual obstruction.

4.2 The four sub-variants: CDW.2 anchor, CDW.1 upside, CDW.3+CDW.4 contingencies

Table 4.1. The four CDW sub-variants. Probability-weighted Expected CoCA across all four ≈ €1,408 bn (post-capture). The operational target is the CDW.1 + CDW.2 hybrid: CDW.2 default trajectory through 2025–2030 with CDW.1 Phase D option preserved for 2030–2032 conditional activation.

Each sub-variant activates a different combination of the Five Compounding Chains framework. Chain 1 — the kill chain — kinetic destruction of Crimean garrison assets through ISR + EW + drones + precision strike. Chain 2 — replacement crisis — Russian inability to replace destroyed equipment through fiscal and demographic depletion. Chain 3 — cost inversion — FPV at $400 vs Iskander at $3M+, neutralising garrison offensive value. Chain 4 — visibility trap — ISR transparency making Russian dispositions permanently exposed. Chain 5 — system versus platforms — integrated NATO–Ukraine system superiority over Russian platform collection. CDW.2 emphasises Chains 2+4+5 for Transnistria; CDW.1 adds Chains 1+3 for Crimea conditional on Phase D triggers; CDW.3 activates all five simultaneously on rupture; CDW.4 operates Chains 4+5 in containment mode.

4.3 Net Strategic Value: all twelve cells positive, CDW.2 dominates every column

Computing Net Strategic Value (NSV) — the single coalition decision criterion that weighs avoided cost against action cost (CoCA). The 4×3 matrix is positive in all twelve cells (range +€595 bn CDW.4 vs PS.1 to +€3,295 bn CDW.2 vs SD.1). Probability-weighted Expected NSV ≈ €1,800 bn NPV 2025–2050 — approximately 8% of EU 2025 GDP, 4% of NATO 2025 GDP — large enough to constitute a first-order policy commitment, not a marginal optimisation. Avoided-cost-to-action-cost ratio ≈ 1.30× at central programme-instrument view, rising to ≈ 2.65× under marginal attribution. CDW.2 institutional-partial dominates every column — highest NSV against PS.1, LO.1 and SD.1; highest E[NSV]/CoCA ratio at 1.47×. The SD.1 column produces 62% of aggregate Expected NSV: the principal political-economy case for CDW is tail-risk avoidance against Cold War 2.0 outcomes, not incremental improvement above the patient-pressure baseline.

The €1,800 bn finding is robust across six perturbation classes. The largest sensitivity is counterfactual baseline (View A vs View B marginal attribution), with upside to €2,330 bn under marginal attribution. NATO 5% accounting produces an envelope €1,450–1,950 bn. The three execution-sensitivity classes (Phase D activation probability, rupture probability, character of rupture) produce small individual sensitivities (€40–60 bn each) and approximately €100 bn aggregate spread. The aggregate envelope across all six perturbations is €1,450–2,330 bn — substantial in magnitude but small relative to the comparison anchors (CoNCD €2,100–4,600 bn). Critically, the sign of Expected NSV never crosses zero. Accounting-convention sensitivities dominate execution sensitivities by approximately 9-to-1 in aggregate spread. The substantive finding is more secure than typical multi-decade benefit-cost analyses where execution uncertainty often inverts the headline conclusion.

4.4 The temporal mismatch and the operational imperative

A structural feature of the CDW programme is the asymmetric timing of cost and benefit. 62% of Expected CoCA falls in the 2025–2035 investment-loaded decade; only 40% of Expected CoNCD-avoided falls in the same decade. Conversely, 60% of avoided benefit accrues in the 2035–2050 capture decade against only 38% of cost. The average outlay-to-realisation lag is approximately 8–12 years. The coalition is asked to invest first and capture later — the binding political-economy constraint operationally addressed through institutional binding mechanisms (Northwood Declaration, Trinity House Agreement, JEF formalisation, UDCG continuity, Coalition of the Willing) designed to outlast individual electoral cycles in major capitals.

5. Synthesis: how the four sections compose

The four sections are not parallel arguments but a single executable chain. Section 1 supplies the legitimacy reservoir that any coalition action requires — combined deprivation is recovery of obligations Russia accepted and breached, not a novel territorial demand, and the structural realist foundation establishes that the deprivation thesis is the only configuration consistent with the 2,500-year empirical record. Section 2 supplies the audience-facing case — €2.1–4.6 trillion of foregone European value, with the regional dimension dominating territorial by 5–7×, framed as benefit being silently foregone rather than intervention requiring justification. Section 3 supplies the executable architecture — a 30-actor coalition map identifying who leads what, the four operational quadrant strategies, the swing-actor and vetogate constraints, and the 2026 H2 – 2027 H1 critical execution window. Section 4 supplies the welfare arithmetic — Expected CoCA ≈ €1,408 bn, Expected NSV ≈ €1,800 bn, ratio 1.30× central / 2.65× marginal, all twelve cells of the sub-variant × best-alternative matrix positive, sign-invariant across all sensitivity classes.

The three policy levers identified in Section 1 (sustaining Western coherence, securing Ukraine 30M+ post-war, preserving Moldovan demographic viability) are the same three levers quantified in Section 2 (€500–1,000 bn of cross-scenario differential), are operationalised in Section 3 through specific actor coalitions (Q1 PROTECT & DEEPEN; UDCG continuity for Ukraine; Cluster 1 sequencing for Moldova), and are priced in Section 4 (Components B, C, E of the CoCA architecture). The four sections describe a single object viewed from four angles — they identify the same operational programme, the same critical window, and the same sub-variant target (CDW.2 central, CDW.1 upside) through four independent analytical methodologies.

The recommendation is unambiguous. CDW.2 institutional-partial is the central anchor — lowest CoCA at €1,305 bn, highest probability at 40%, regret-minimising configuration, dominates every column of the NSV matrix. CDW.1 kinetic sequencing is the upside option — adds Crimean recovery on softening nuclear ceiling at +€175–350 bn premium; the option-preservation case dominates the unconditional-dominance case. CDW.3 rupture preparedness is dual-use with CDW.2 sustainment — highest expected return per Euro of incremental coalition investment. CDW.4 chaotic is the failure-mode of CDW.3 — structurally the weakest sub-variant but still positive welfare. The operational target is the CDW.1 + CDW.2 hybrid: CDW.2 default trajectory through 2025–2030 with CDW.1 Phase D option preserved for 2030–2032 conditional activation. The Tier-1 lead actors are continuous across sub-variants — UK + France co-anchor, USA institutional backbone, EU Commission for Chapter 31 + sanctions, Germany OSCE chair, Poland–Romania frontier, Ukraine + Moldova as recipients — meaning coalition-building investment through 2025–2030 is largely sub-variant-neutral and pays returns under any sub-variant.
