Russia has escalated its rhetoric against Lithuania following discussions in the Lithuanian Parliament regarding potential constitutional amendments to allow the storage of nuclear weapons for national security. 

Initially, Kremlin spokesperson Dmitry Peskov issued warnings regarding European energy costs and stated that Russia would target Lithuanian territory with nuclear weapons if the nation hosts allied warheads. 

This tension intensified when former Russian President Dmitry Medvedev claimed that Lithuania could ‘disappear from the map of the world’ in a conflict. Medvedev further asserted that NATO allies would not intervene to defend the Baltic state, arguing that invoking Article 5 would result in a ‘global, planetary catastrophe’ and that collective defense mechanisms would not be applied.
