France and UK Consider Deploying 10,000 European Soldiers to Anchor Europe’s Post-War Security in Ukraine

Paris: French President Emmanuel Macron has held internal discussions on the possible deployment of around 10,000 European soldiers to Ukraine as part of post-war security guarantees, signaling one of the most ambitious European military concepts yet tied to ending the conflict with Russia. The proposal, discussed during a closed-door meeting with senior figures from Macron’s political camp, centers on the formation of two multinational brigades that would form the backbone of a future European Union “deterrence force.”

According to accounts of the meeting, the brigades would be embedded within a broader multinational framework led jointly by France and the United Kingdom. The notional command element for the force would be based at Mont Valéry (Mont Valérien) near Paris, a site with longstanding military and symbolic significance for France. Participants were also briefed on the types of weapons and equipment the brigades could field, though no final decisions have been taken.

At the conclusion of the meeting, Macron and France’s Minister of the Armed Forces Sébastien Lecornu agreed that the issue could not proceed without parliamentary scrutiny. Lecornu later indicated that a debate—with or without a formal vote—would be organized within 15 days to three weeks, reflecting the political sensitivity of deploying European troops on Ukrainian soil even after active hostilities end.

British-French Core, Numbers Still Fluid

Additional details were offered publicly by Matilde Panot, leader of the left-wing LFI (La France Insoumise). She stated that the proposed two-brigade deployment would amount to just under 10,000 soldiers, structured around a British-French contingent, with roughly half of the personnel potentially drawn from the French Army.

Notably, the figure discussed is smaller than the total NATO forces currently stationed on Europe’s eastern flank in the Baltic States, Romania, and Poland. This has fueled speculation that the concept remains a baseline proposal, with room for additional European contributors once political conditions and security guarantees are clarified. Officials involved in the talks have not confirmed whether troops from Germany, Italy, Poland, or other EU members were explicitly discussed at this stage.

Earlier Franco-British-Ukrainian Framework

The internal French discussions follow an earlier, publicly acknowledged step. Ukraine, France, and the United Kingdom previously signed a declaration of intent outlining cooperation on the future deployment of multinational forces in Ukraine once conditions allow. That declaration emphasized deterrence, training, and long-term stabilization rather than direct combat operations, aligning with Kyiv’s calls for durable security guarantees short of immediate NATO membership.

What Would a European Brigade Look Like?

Military planners note that the 5,000-soldier figure per brigade corresponds closely to a reinforced British Army brigade, which typically fields 3,000 troops in peacetime and can expand to around 5,000 before deployment. French Army brigades, by contrast, are generally larger even in their standard configuration. The 2nd Armored Brigade numbers roughly 6,800 soldiers, while the 6th Light Armored Brigade reaches about 7,500, suggesting that any Franco-British compromise would require structural adjustments.

In terms of equipment, analysts consider a fully armored brigade unlikely. France and the United Kingdom together operate fewer than 450 main battle tanks—approximately 222 French Leclercs and 227 British Challenger 2s—limiting the feasibility of committing large armored formations abroad. A mechanized or light infantry-centric brigade, supported by artillery, air defense, drones, and logistics units, is widely viewed as a more realistic option. Final decisions on structure and armament are expected to emerge only after detailed joint planning with London and consultations with potential partner states.

Role of the “Coalition of the Resolute”

The proposed brigades would operate alongside a wider grouping informally referred to by European officials as the Coalition of the Resolute. Beyond any ground presence, coalition plans include sending logistics experts, weapons specialists, and military trainers to assist in rebuilding and reforming the Ukrainian Armed Forces after the war.

Airpower is another central pillar. Coalition air forces, working in coordination with the Ukrainian Air Force, would help secure Ukrainian airspace, a move intended to bolster civilian safety and enable the resumption of international commercial air traffic. European officials argue that visible air patrols would serve as a powerful deterrent without crossing the threshold into offensive operations.

Particular emphasis is also being placed on the Black Sea, where a reinforced task force involving Turkey, Romania, and Bulgaria would focus on demining operations and maritime security. Clearing sea lanes is seen as essential for restoring safe, uninterrupted access to Ukrainian ports, a critical factor for global food exports and Ukraine’s economic recovery.

Moscow Reacts Sharply

The discussions have drawn an angry response from Moscow. Former Russian president and current Security Council deputy chairman Dmitry Medvedev accused European leaders of pushing the continent toward a wider conflict. In a statement posted on X (formerly Twitter), Medvedev said Russia would “not allow any European or NATO troops in Ukraine,” dismissing Macron’s ideas as reckless.

Medvedev accompanied his remarks with footage of a recent Oreshnik missile strike on Lviv, claiming the system—described by Russian sources as carrying no conventional warhead and relying on kinetic energy elements—was intended as a warning to Europe. Western analysts note that the strike missed its intended target and caused limited damage, but Medvedev argued it would be enough to frighten European governments into abandoning the January 6 security declaration, which envisions ending the war through guarantees and a European military presence.

Strategic Gamble for Europe

For Paris, the proposal reflects Macron’s long-standing push for greater European strategic autonomy and a more assertive EU role in continental security. For critics, it raises questions about escalation, legal authority, and public support at a time when many European militaries are already stretched.

With parliamentary debate imminent and allied consultations still underway, the idea of a 10,000-strong European deterrence force remains a concept rather than a commitment. Yet the discussions themselves underscore a shifting reality: European capitals are increasingly planning not just for how the war in Ukraine ends, but for how the peace—if and when it comes—will be enforced.
