Trump’s U-Turn seems partly the result of European leaders, Rutte especially, who worked hard to develop common ground with the U.S. President. It also seems to be the result of growing irritation with Putin. Trump said Monday that Putin talks “so beautifully” when it comes to a ceasefire but “then he’ll bomb people at night. We don’t like that.”

The president announced the US will send additional Patriot air-defense systems to Ukraine, part of a European Union–funded deal.
