Putin has increased tensions regarding Ukraine by suspending the START nuclear pact.

Russian President Vladimir Putin suspended Moscow’s participation in the last remaining nuclear arms control pact with the U.S., announcing the move Tuesday in a bitter speech where he made clear he would not change his strategy in the war in Ukraine.

In his long-delayed state-of-the-nation address, Putin cast his country — and Ukraine — as victims of Western double-dealing and said it was Russia, not Ukraine, fighting for its very existence.

“We aren’t fighting the Ukrainian people,” Putin said in a speech days before the war’s first anniversary on Friday. “The Ukrainian people have become hostages of the Kyiv regime and its Western masters, which have effectively occupied the country.”
