Medvedev Threatens Lithuania, Claims NATO Won't Invoke Article 5

Medvedev escalates rhetoric, threatening Lithuania's existence over its nuclear weapons ban lift and asserting NATO would not invoke Article 5, risking a 'global catastrophe.' This is a continuation of Russian nuclear saber-rattling, but the specific targeting of a NATO member and the claim of alliance weakness mark an escalation. The claim about Article 5 is unverified and likely aimed at deterrence and domestic audience.
