Russian President Vladimir Putin could win the war in Ukraine “on the battlefield by the end of 2024” if Congress continues to withhold military assistance, according to CIA Director Bill Burns.

“Without supplemental assistance, the picture is a lot more dire,” Burns said Thursday at the George W. Bush Presidential Center in Texas. “There is a very real risk that the Ukrainians could lose on the battlefield by the end of 2024 — or at least put Putin in a position where you could essentially dictate the terms of a political setup.”
