European leaders met in London to formulate a plan to help end the war in Ukraine. But even potential peacekeepers face political and economic hurdles.

President Donald Trump said Europe made loans and the United States did not, but that’s not accurate. “Just so you understand, Europe is loaning the money to Ukraine. They get their money back.”

European leaders sought to assemble what Britain called a “coalition of the willing” to secure Ukraine after any US-brokered ceasefire, as they gathered in London to coordinate defense spending hikes amid concerns of an American pullback.
