New York Times: The CIA director says there is no evidence to suggest Putin is preparing to use nuclear weapons, but lack of results in Ukraine may tempt him.

The director of the CIA, William J. Burns, said that in an attempt to secure a victory, Russian dictator Vladimir Putin may "use a tactical or low-yield nuclear weapon" as the military campaign in Ukraine fails to achieve strategic goals. He cautioned that so far he had seen no “practical evidence” of the kinds of military deployments or movement of weapons that would suggest such a development was imminent.
