Dmitry Medvedev left no room for interpretation - drone factories across Europe are legitimate military targets for Russia. The list of facilities in Britain, Germany, and other countries producing UAVs for Ukraine is, according to him, 'a roster of possible targets for Russian armed forces.'

Timing of a strike? 'Depends on future developments,' Medvedev said, which translates to: when Moscow decides it's enough. Russia's military establishment views Europe's increased drone production as a direct escalation - Europe, they say, is turning into Ukraine's 'strategic rear area.'

Britain is at the top of the list. Its factories produce the bulk of drones ending up on the Ukrainian front. Germany follows. Russian media are already detailing potential targets, and analyst Boris Rozhin went a step further - calling European states 'direct sponsors of state terrorism.'

Is this a real threat or another round of Russian rhetoric designed to sow fear? One thing is certain: when Medvedev publicly names factories as military targets, it's not a casual statement. In the Balkans, we know well what it means when someone starts naming targets.

The question isn't whether Russia can strike European soil. The question is how far Europe is prepared to go in supporting Ukraine - and whether it has truly calculated the risk.
