Russian President Vladimir Putin is not a “sentimentalist” when it comes to the massive loss of life his troops are facing in Ukraine and believes he can exhaust Ukraine and the West and ultimately win the war, CIA Director Bill Burns said Sunday.

Burns, speaking on CBS’s “Face the Nation,” said the United States must provide full material and intelligence support in coming months to “puncture that hubris on Putin’s part” and regain momentum on the battlefield. He said Putin is convinced he “can’t afford to lose” so he will attempt to drag out the war.

“Putin’s view of Americans, of us, has been that we have attention deficit disorder, and we’ll move on to some other issue eventually,” Burns said. “So instead of looking for ways to either back down or find a famous off ramp, you know, what Putin has done is double down.”

Friday marked a grim milestone: one year since Russia invaded Ukraine. During this time, the U.S. pledged about $113 billion in assistance to Kyiv, more than half in the form of military aid, according to the U.S. Department of Defense. 

Amid domestic struggles ranging from spiraling living costs to rising refugee arrivals, polls show Americans are growing less enamored with providing arms to Ukraine.
