Estonian Prime Minister Kaja Kallas said Ukraine still has a path to victory and allies can help it defeat Russian forces by contributing a chunk of their economic output to the war effort.

Every member of the so-called Ramstein group — more than 50 countries including all 31 members of the North Atlantic Treaty Organization — should channel the equivalent of 0.25% of their gross domestic product to Kyiv annually, Kallas said. That would raise at least €120 billion ($131 billion) and swing the conflict in Ukraine’s favor, she said.
