European Commission President Ursula von der Leyen says Ukraine must win the war it is fighting against Russia, making President Vladimir Putin’s decision to invade a “strategic failure”.

Moscow is “treating millions of people not as human beings but as faceless populations to be moved or controlled or set as a buffer between military forces, trying to trample the aspirations of an entire nation with tanks,” von der Leyen told the WEF conference in Davos.

“Ukraine must win this war, and Putin’s aggression must be a strategic failure,” she added.
