Executive Summary

At the Paris summit of September 4, 2025, European leaders—encouraged by President Trump—committed to providing Ukraine with postwar security guarantees. A coalition of 26 nations agreed to form a “reassurance force” to be deployed only after a ceasefire, combining land troops, naval presence in the Black Sea, and air protection. France and the UK will spearhead the European contingent. The United States pledged no ground troops but promised air support and intelligence assistance. Some countries (e.g., Italy, Bulgaria) ruled out troop deployments but will contribute to ceasefire monitoring and maritime security.

This marks the formal operationalization of the “Coalition of the Willing” first launched in London (March 2025), transforming European promises into concrete commitments, with the U.S. in a supportive—but non-leading—role.

Five Laws of Epistemic Integrity

1. Truthfulness of Information
   Verified by multiple major outlets (WaPo, Reuters, AP). Macron’s public statement confirmed the 26-nation commitment, with details on France/UK leadership. 🟢 High Integrity

2. Source Referencing
   Coverage from three primary sources with direct citations of Macron, U.S. envoy Witkoff, and state officials. No reliance on anonymous leaks. 🟢 High Integrity

3. Reliability & Accuracy
   Numerical claims (26 countries, conditional ceasefire deployment, $-undefined commitments) are consistent across Reuters and AP. Minor variations (degree of Italian/Bulgarian involvement) reflect nuance, not contradiction. 🟢 High Integrity

4. Contextual Judgment
   Correctly situates this move within the framework of the London 2025 summit and the Coalition of the Willing. Recognizes conditionality on ceasefire to avoid escalation with Russia. 🟢 High Integrity

5. Inference Traceability
   Inferential chains (Europe’s strategic autonomy, U.S. symbolic backing, conditional deployment) are supported by cross-referenced statements. Minimal speculative gaps. 🟢 High Integrity

Structured Opinion – BBIU Analysis

European Coalition, U.S. Airpower, and the Fractured Architecture of Postwar Guarantees for Ukraine

The Paris summit of September 4, 2025, has been framed as a turning point in Europe’s willingness to assume responsibility for Ukrainian security. Yet a deeper structural reading reveals something closer to a reenactment of the 춘추전국시대 (Spring and Autumn / Warring States period): a fragmented system of asymmetric commitments, hegemonies competing for symbolic leadership, and hidden financial pathways that ultimately define the real distribution of power.

1. The Frontier as Destiny

For Poland, Romania, Slovakia, Hungary, Finland, and the Baltic states, the question is existential. If Ukraine collapses, their borders become the immediate line of contact with Russian forces.

• Poland is investing massively in U.S. and Korean armor precisely because it sees itself as the next battlefield.

• Romania understands the Black Sea dimension: Russia’s consolidation in Crimea and Odessa would project maritime pressure directly into the Danube delta.

• Finland and the Baltics consider Ukrainian defeat equivalent to a prelude to their own vulnerability. Their contribution to the coalition, therefore, is less symbolic than a survival reflex.

2. The Central European Dilemma

Germany, Austria, Czechia, and Bulgaria face immediate strategic rather than existential risk. A collapse in Ukraine would unleash refugee flows, destabilize energy supply chains, and undermine industrial security. Yet these states hesitate to commit combat troops:

• Germany, despite its massive rearmament funds, continues to be constrained by political caution and logistical fragility.

• Austria hides behind neutrality, but geography ensures exposure to eastward pressure.

• Bulgaria, with a Black Sea coastline, would find itself in a direct line of maritime intimidation if Russian dominance expands.

This zone lives in contradiction: it understands the consequences but resists the costs of early deterrence, betting on delay rather than irreversible commitments.

3. The Western Theater of Symbolism

France and the UK carry the mantle of 霸者 (paeja, hegemon) within the coalition. Their leadership is less about volume of troops and more about maintaining European credibility as a military actor:

• France anchors with its nuclear deterrent and expeditionary forces.

• The UK projects with carriers and intelligence networks.

But beyond these two, the Western and Southern members—Italy, Spain, Portugal, Greece, Ireland—are participating for reasons of legitimacy rather than survival. Their risk exposure is primarily reputational (failing Europe, failing NATO) and economic (energy dependence, refugee costs), not territorial.

4. The Invisible Layer: Money and Industry

The coalition’s strength is not in numbers of brigades but in financial transfers and defense-industrial contracts.

• U.S. leverage resides in control of ISR (intelligence, surveillance, reconnaissance), drones, and long-range strike. Washington supplies the strategic backbone without committing ground forces, thereby ensuring decisive influence at minimal domestic risk.

• European states unwilling to send troops compensate with money: Italy and Bulgaria already pledged funds and naval monitoring rather than ground combat units.

• Defense industries—Lockheed Martin, Raytheon, BAE, Dassault, Rheinmetall—are the silent beneficiaries. For many coalition members, joining the “26” means securing procurement slots, subsidies, or reconstruction contracts rather than preparing for combat.

Here the maxim applies with full force: if you want to catch the real decision-maker, follow the money.

5. The Paradox of Collective Unity

The “Coalition of the Willing” is not NATO. It lacks Article 5 and thus operates as a confederation of convenience. The Paris declaration is less a military order of battle than a staged act of European unity. Beneath the façade:

• A core of real fighters (France, UK, Poland, Romania, Baltics, Finland).

• A middle layer of hesitant strategists (Germany, Austria, Czechia, Bulgaria).

• A periphery of symbolic signatories (Italy, Spain, Portugal, Greece, Netherlands, Belgium, Denmark, Ireland).

This mirrors the 춘추전국시대: hegemon states sought coalitions under banners of unity, but most participants joined for cover while pursuing their own survival calculus.

6. The Role of the United States: Zhou Without Empire

In classical China, the Zhou king retained ritual authority but ceded real power to hegemonic states. The U.S. today occupies the same position:

• Trump plays the “ritual emperor”—with legitimacy and symbolic sanction.

• France and the UK act as hegemon states, taking risk at the frontier of European credibility.

• Smaller members behave as vassals, balancing outward obedience with inner autonomy, keeping channels open to both Washington and, discreetly, Moscow.

This layered system ensures that the coalition looks formidable in communiqué form, but fractures instantly under the strain of combat or escalation.

Annex — Ukraine’s Economy: Pre- and Post-War, and the U.S./EU Position

A. Pre-war snapshot (≈2019–2021)

• Sectoral structure: services ~60% of GDP; industry (incl. construction) ~19–23%; agriculture ~7–11% (World Bank WDI).

• Donbas as industrial/export core: Donetsk+Luhansk accounted for ≈14–16% of GDP and ~25–30% of exports in 2013.

• Energy: the Zaporizhzhia Nuclear Power Plant (ZNPP) generated ~20% of national electricity; nuclear was ~55% of the mix in 2021.

• Ports: ~157 Mt cargo in 2021; grains and iron/steel were top commodities.

B. Shocks 2022–2025 and “starting point” for post-war

• ZNPP offline → ~20% electricity gap to be covered by EU imports/renewables/grid balancing.

• Irrigation: destruction of the Kakhovka dam left ~0.58–0.60 Mha without irrigation; agricultural exports hit by lost irrigated lands/flooding.

• Ports/trade: partial reopening of the Black Sea corridor pushed 2024 throughput to 97.2 Mt (+57% y/y) but still −36.8% vs 2021; by 2025, the “sea corridor” accumulated 120 Mt since launch.

• Reconstruction needs: US$486 bn (RDNA3, 2024) → US$524 bn (RDNA4, Feb 2025), ~2.8× Ukraine’s 2024 GDP.

• Growth: fragile recovery; EBRD forecast for 2025: 3.3% growth with war still ongoing.

C. Post-war/case of ceasefire (baseline scenario)

Product mix changes

• Less “nuclear + steel + heavy industry”, more “services + continental agriculture + light manufacturing”; services already ~60% and will rise if heavy industry remains occupied.

• Agriculture: export capacity remains thanks to Black Sea corridor and EU logistics, but bottlenecks from irrigation loss (Kakhovka) and higher costs.

• Ports: 2024 = 97.2 Mt vs 157.3 Mt in 2021 → ~60 Mt gap still constraining grain/mineral revenues.

Territory & GDP

• The five disputed regions (Crimea, Donetsk, Luhansk, Zaporizhzhia, Kherson) concentrated critical industry, energy, and irrigated agriculture. Donbas alone ≈14–16% of GDP (2013). Kherson ≈2% of GDP; Crimea smaller but strategically important for ports/tourism/energy.

Bottom line: a reduced Ukraine becomes relatively more services + continental agriculture, with a fragile energy grid and truncated heavy industry, until reconstruction investments (energy, transport, defense) arrive.

D. Who finances, and under what conditions?

European Union

• Ukraine Facility 2024–2027: €50 bn (≈€33 bn loans + €17 bn grants) tied to the “Ukraine Plan,” with quarterly disbursements.

• SAFE – €150 bn “loans-for-arms” fully subscribed by 19 member states.

• Military aid increasingly via industrial contracts rather than stockpiles (Kiel Institute).

• Frozen Russian assets: G7 loan of US$50 bn backed by interest income; ongoing debate on the principal.

United States

• Enabler role: ISR, air defense (Patriot sustainment), comms (Starlink), missiles; no boots on the ground, pushing Europe to pay more (Trump line, 2025).

• G7 loan tranche: ~US$20 bn share of the US$50 bn package backed by Russian asset proceeds.

• Rules of engagement: wavering over whether U.S. weapons can strike into Russia; signals careful escalation management.
