Bulgaria just became the first NATO member to formally walk away from the coalition of nations directly arming Ukraine against Russia.

Prime Minister Rumen Radev framed the decision as a pivot toward diplomacy and national security priorities. The country will stop supplying weapons from government stockpiles to Kyiv, effectively ending a pipeline that has delivered 13 packages of military assistance since Russia’s full-scale invasion began in 2022.

What Bulgaria is actually doing

Bulgaria is halting state-level military transfers, meaning no more arms from government reserves heading east. But the country’s private defense industry can still sell weapons commercially to Ukraine.

Defense Minister Dimitar Stoyanov and Radev have positioned the shift as necessary for Bulgaria’s own security posture and economic stability. The argument goes something like this: Bulgaria needs to rebuild its own depleted military stocks rather than shipping them abroad, and continued involvement risks escalation that Sofia would rather avoid.
