CIA: ‘We don’t know’ if Putin will use force in Ukraine

Speaking to the Wall Street Journal annual CEO conference, William Burns also added we do know that Vladimir Putin "is putting the Russian military, the Russian security forces where they could act in a pretty sweeping way."

U.S. President Joe Biden and Russian President Vladimir Putin are to hold a video call on Tuesday (December 7) as the U.S. tries to head off Russia from launching military action against Ukraine, after Moscow massed tens of thousands of troops on the Ukraine border.

Biden will warn Putin of severe economic consequences should Russia go ahead with an invasion of Ukraine, a senior U.S. administration official said.
