Russia has issued a stark nuclear warning to Lithuania as tensions with NATO rise across the Baltic flank.

The warning comes as Vilnius moves to scrap its constitutional ban on weapons of mass destruction, potentially opening the door to a future European nuclear-sharing arrangement. Germany is also deploying a heavy tank brigade in Lithuania near Russia. With NATO strengthening its eastern flank, is Europe testing one of Putin’s most dangerous red lines?
