Vladimir Putin has threatened to hit Kyiv with “all the means of destruction at Russia’s disposal” if Ukraine receives nuclear weapons from the US.The Russian leader was responding to a New York Times report quoting unidentified officials as suggesting Joe Biden could give Ukraine nuclear weapons before he exits office in January.

Three experts spoke to Newsweek about the possibility of Moscow firing nuclear weapons into Ukraine as tensions escalate.

Putin's goals in Ukraine remain the same: weakening Ukraine's ties to NATO, hindering Ukrainian nationalism and territorial gains.
