The War After the War: How Russia’s Veterans Could Become Europe’s Problem.
European governments are facing renewed warnings that a potential ceasefire in Ukraine could trigger a new phase of security instability across the continent, as Russia seeks to redirect former combatants into hybrid operations inside the European Union.
Estonia’s Foreign Minister Margus Tsahkna said Russia could send hundreds of thousands of ex-soldiers into Europe after any halt in fighting, using them to carry out sabotage, criminal activity and destabilization efforts. Speaking on the sidelines of meetings in Brussels, Tsahkna described the threat as urgent and unprecedented, urging the EU to act before the war formally ends.
“We have close to one million combatants in Russia right now,” Tsahkna said, warning that many of them were recruited from prisons and had violent criminal backgrounds. He argued that Moscow would not want such individuals returning home and could instead “weaponize” them as part of a broader hybrid campaign against Europe.
Estonia has proposed a blanket ban preventing Russian soldiers who fought in Ukraine from entering the EU’s Schengen free-travel zone, which covers 29 countries. The proposal would also restrict work visas and residence permits for former combatants. Tsahkna said several EU partners had responded positively to the idea, and political guidance could be issued at upcoming European summits.
The warning reflects growing concern that Vladimir Putin could use any pause in the Ukraine war to intensify pressure on Europe through non-military means. European security services have already linked Moscow or its proxies to a rise in sabotage, arson and covert operations since Russia’s 2022 invasion of Ukraine, though the Kremlin denies responsibility.
Estonian intelligence assessments suggest that up to 180,000 convicted prisoners were recruited directly from Russian penal colonies to fight in Ukraine. According to officials, crime rates in Russia have surged as some veterans returned home, reinforcing fears that others could be directed abroad.
“These individuals are perfect for hybrid operations,” Tsahkna said, citing their experience with violence and their vulnerability to recruitment by Russian security services.
The concerns extend beyond Estonia. Several EU countries and the United Kingdom have reported an increase in suspected Russian-linked incidents, including attacks on infrastructure and politically sensitive targets. Analysts say such actions are designed to undermine public confidence and strain internal security systems without triggering a conventional military response.
While NATO remains focused on deterring direct military aggression from Russia, officials acknowledge that hybrid threats fall largely outside traditional defense planning. The prospect of large numbers of former fighters moving freely across Europe has raised questions about the bloc’s preparedness for post-war risks.
Tsahkna said Estonia has already imposed entry bans on hundreds of suspected ex-combatants and has begun sharing intelligence with partners. He called on non-Schengen countries, including the UK, to coordinate closely with the EU to prevent potential security gaps.
“We need to do this now,” he said. “Europe is not ready for peace if peace means a new kind of insecurity.”
EU officials have not yet announced a collective decision, but discussions are expected to intensify as diplomatic efforts toward a Ukraine settlement continue.
