As the fourth anniversary of Russia's invasion approaches, a 30-nation coalition prepares for the most consequential European military deployment since Bosnia—with or without a peace deal
Executive Summary
- The UK-France-led "Coalition of the Willing," now formally titled Multinational Force Ukraine (MFU), has grown to over 30 nations planning to deploy military forces on Ukrainian soil—the largest European-led expeditionary commitment since IFOR in Bosnia (1995).
- Former PM Boris Johnson's call to deploy troops before a ceasefire—rather than after—represents a radical escalation of the concept, transforming a peacekeeping framework into a deterrence posture that would fundamentally alter the war's dynamics.
- With Geneva peace talks stalled and the 4th anniversary of the invasion on February 24, Europe faces an existential choice: whether the MFU becomes Europe's strategic insurance policy or its greatest provocation since NATO expansion.
Chapter 1: From Concept to Command Structure
The idea of European troops in Ukraine seemed unthinkable when French President Macron first floated the concept in March 2025. He was widely criticized, even within his own alliance. A year later, the proposal has quietly transformed from diplomatic trial balloon into operational reality.
In January 2026, the UK and France signed a Declaration of Intent with Ukraine—a document that, while short of a treaty obligation, commits both nations to deploy military forces on Ukrainian territory in the event of a peace agreement. The forces would conduct deterrence operations across all domains: land, sea, and air. They would also train, plan, and regenerate Ukraine's armed forces.
The coalition has expanded to over 30 nations, led jointly by London and Paris. Germany, while not committing ground forces, has assumed co-leadership of the Ukraine Defence Contact Group alongside the UK. The E5 grouping (UK, France, Germany, Italy, Poland) has emerged as the coalition's strategic steering committee, with German Defence Minister Boris Pistorius suggesting it could evolve into a "European Five Eyes"—an intelligence-sharing alliance independent of Washington.
The UK Ministry of Defence has already allocated £200 million to prepare British military units for potential Ukraine deployment. A half-billion-pound air defence package was delivered just last week. These are not hypothetical budget lines—they are operational preparations for a deployment that planners believe could materialize within months.

Chapter 2: Johnson's Radical Gamble—Deploy Now
On February 22, in an interview with the BBC's Laura Kuenssberg, former Prime Minister Boris Johnson made a provocative argument that shattered the coalition's careful diplomatic framing: if European nations are willing to deploy troops after a ceasefire, why not do it now?
"If we can have boots on the ground after the war, after Putin has condescended to have a ceasefire, then why not do it now?" Johnson argued, alongside former Chief of the Defence Staff Admiral Sir Tony Radakin.
Johnson's logic is disarmingly simple. The current framework hands Vladimir Putin a veto: troops arrive only after Russia agrees to stop fighting. This means the coalition serves as a reward for Russian compliance rather than a deterrent against Russian aggression. By deploying to "peaceful regions in non-fighting roles," Johnson argues, Europe could "flip a switch" in Putin's calculations—demonstrating that the cost of continued aggression includes direct confrontation with European military forces.
Admiral Radakin offered a complementary critique, describing the West's approach throughout the war as "incrementalism"—always delivering weapons too late, always one step behind Ukraine's requests. "It's too slow and it's deeply frustrating," he said. "These tensions have existed all the way through."
This echoes a pattern that has defined the war: HIMARS, Leopard 2 tanks, F-16 fighters, Storm Shadow missiles, ATACMS—each was initially refused, then agonizingly debated, then finally delivered months after it could have been decisive. The "incrementalism trap" has become the war's defining strategic failure.
Johnson's proposal would break this pattern by deploying the ultimate escalation tool—European military personnel—preemptively rather than reactively. But it carries enormous risks.
Chapter 3: The Stakeholder Calculus
Russia: Red Lines and Bluffs
Putin has consistently framed any Western military presence in Ukraine as a casus belli. Kremlin spokesperson Dmitry Peskov has warned that European troops would become "legitimate targets." Russia's nuclear doctrine, revised in November 2024, explicitly lowers the threshold for nuclear use if a nuclear-armed state (or its allies) attacks Russian territory.
Yet Russia's actual behavior has repeatedly shown flexibility behind the rhetoric. NATO weapons, intelligence, and training have been flowing into Ukraine for four years without triggering the promised escalation. The Kremlin has absorbed each Western escalation step—from Javelins to ATACMS to long-range strikes on Russian territory—with verbal protests but no kinematic response against NATO members.
The critical question: Would European non-combat troops in western Ukraine represent a qualitatively different provocation? The answer likely depends on their proximity to combat zones and their role in enabling Ukrainian operations.
Ukraine: The Security Guarantee It Always Wanted
For Kyiv, the MFU represents the closest thing to the NATO Article 5 guarantee that formal alliance membership would provide. Zelenskyy's negotiating team has consistently demanded security guarantees as the price for any territorial concessions. A 30-nation military presence on Ukrainian soil would constitute the most credible non-NATO security guarantee available.
Zelenskyy's February 20 statement was telling: he called for another round of talks "very soon, as early as this February" and insisted that "Europe is actively engaged in the process of ending the war" and its role "must grow." The MFU gives Europe leverage that purely diplomatic engagement cannot provide.
The United States: Conspicuously Absent
Washington has pointedly declined to join the coalition. The Trump administration's approach—bilateral negotiations with Russia, the June deadline, the Dmitriyev economic package—treats the war as a US-Russia bilateral issue in which Europe is a secondary actor. The MFU represents Europe's assertion that it will not accept a peace deal imposed over its head.
This creates a paradox: the MFU simultaneously strengthens Europe's negotiating position and widens the transatlantic gap. If Europe deploys troops that the US refuses to back with Article 5 guarantees, the MFU could become the world's most expensive tripwire—triggering obligations that NATO collectively may not honor.
Chapter 4: Scenario Analysis
Scenario A: Post-Ceasefire Peacekeeping Deployment (45%)
Premise: A ceasefire is negotiated (possibly by mid-2026), and the MFU deploys as planned along a demilitarized zone or buffer area.
Historical Precedent: IFOR/SFOR in Bosnia (1995-2004). NATO deployed 60,000 troops to enforce the Dayton Accords. The operation was broadly successful—no return to full-scale combat—but the underlying political issues remain unresolved 30 years later.
Why 45%: This remains the most likely outcome because it aligns with all parties' stated preferences. The EU, UK, and France are explicitly preparing for this scenario. Russia would prefer a frozen conflict (favorable to its current territorial gains) over continued war. The main obstacle is agreeing on terms—particularly the status of occupied territories and Ukraine's future alignment.
Trigger Conditions:
- Geneva talks produce framework agreement by April-May
- Trump-Putin leaders' meeting yields territorial compromise
- Russia's economic deterioration (oil revenues down 65%, manpower crisis) forces concessions
Scenario B: Pre-Ceasefire Deployment (Johnson Model) (15%)
Premise: European nations deploy non-combat personnel to western Ukraine before any agreement, as Johnson proposes.
Historical Precedent: No precise parallel exists. The closest analogy is the "tripwire" concept from Cold War Berlin—small Western garrisons whose military value was symbolic but whose political significance was existential. Their destruction would guarantee full NATO involvement.
Why 15%: This scenario requires political courage that European leaders have consistently failed to demonstrate. The UK government's immediate response to Johnson's proposal was cautious: they touted their support but did not endorse immediate deployment. The risk of Russian escalation—even if historically unlikely—is one that risk-averse European democracies will struggle to accept. The probability increases if peace talks collapse entirely by summer 2026.
Trigger Conditions:
- Geneva talks collapse definitively
- Major Russian escalation (chemical weapons, nuclear facility strike)
- Shift in US posture that makes European action existentially necessary
Scenario C: MFU Remains Paper Exercise (30%)
Premise: The coalition never deploys. Peace talks drag on, the war continues as a frozen conflict, and the MFU becomes a diplomatic tool rather than an operational force.
Historical Precedent: The European Rapid Reaction Force announced in 1999 was supposed to give Europe independent military capability. Twenty-seven years later, the EUFOR missions remain small-scale peacekeeping operations, not the strategic force originally envisioned.
Why 30%: European defense promises have a long history of underdelivery. The 2% GDP NATO spending target took 20 years for most members to approach. The MFU faces massive logistical challenges: interoperability between 30 national armies, rules of engagement in a hot war zone, political sustainability across multiple election cycles. If Russia maintains pressure without escalating dramatically, the MFU could wither from political fatigue.
Trigger Conditions:
- War continues at current intensity without resolution
- European elections produce governments hostile to Ukraine commitment
- US-Russia bilateral deal that bypasses European coalition entirely
Scenario D: Escalation to NATO-Russia Confrontation (10%)
Premise: MFU deployment (pre- or post-ceasefire) triggers direct Russian military action against coalition forces, risking broader conflict.
Historical Precedent: The 1983 Beirut barracks bombing, which killed 241 US Marines deployed as peacekeepers and led to Western withdrawal from Lebanon. Also relevant: the 2016 Turkish shootdown of a Russian Su-24, which demonstrated that NATO-Russia incidents can be contained.
Why 10%: Russia's nuclear arsenal makes deliberate escalation suicidal, and Putin has consistently avoided direct confrontation with NATO forces. However, the risk of accidental escalation—a missile strike near MFU positions, a drone collision, friendly fire in fog-of-war conditions—is non-trivial. The more forces deployed, the greater the probability of incidents.
Chapter 5: Investment Implications
Defense Sector: The Super-Cycle Continues
The MFU accelerates Europe's rearmament super-cycle. The EU's SAFE bond program (€150B+), NATO's 5% GDP target, and the E5 coordination mechanism all create sustained demand for European defense manufacturers.
Key beneficiaries:
- BAE Systems (UK lead contractor, naval and land systems)
- Thales (French electronics, communications, command systems)
- Leonardo (Italian aerospace, rotorcraft for MFU logistics)
- Rheinmetall (German armored vehicles, ammunition—even without German ground troops)
- PGZ Group (Polish defense, eastern flank logistics hub)
Historical comparison: IFOR/SFOR deployments in the 1990s generated sustained procurement cycles for 8-10 years. The MFU, if deployed, would be significantly larger in scope and duration.
Currency and Bond Markets
A pre-ceasefire deployment (Scenario B) would likely trigger:
- EUR weakness (risk premium) in the short term
- GBP volatility (UK political risk)
- Safe-haven flows into gold (already $5,000+) and Swiss franc
- JGB/Bund spread widening as fiscal commitments expand
A post-ceasefire deployment (Scenario A) would be more muted—already partially priced in through defense spending commitments.
Energy
Any deployment scenario increases the premium on European energy security. The EU's gas storage crisis (35% minimum), combined with the strategic vulnerability of forces dependent on imported energy, strengthens the case for:
- LNG infrastructure acceleration
- Nuclear renaissance (SMR deployments)
- Strategic petroleum reserve rebuilding
Conclusion
The Multinational Force Ukraine represents the most significant European military commitment since the end of the Cold War. Whether it deploys before or after a ceasefire—or never deploys at all—its very existence has already reshaped the strategic landscape. Europe is preparing, for the first time since 1945, to project military power eastward on its own initiative, without American leadership.
Boris Johnson's provocation—deploy now, don't wait for Putin's permission—captures the central tension. The incrementalism that Admiral Radakin lamented has cost lives and emboldened Moscow. But the alternative—immediate deployment into an active war zone—carries risks that no European leader has been willing to accept.
The answer will likely emerge not from bold strategic vision but from events: if Geneva talks collapse, if Russia escalates, if the 4th anniversary of the invasion passes without progress, the political pressure to act will intensify. The MFU's 30 nations have prepared the instrument. The question is whether they will have the courage to use it.
