The prime minister wants to keep everyone happy. He has been loath to criticize Trump, has warmed up Britain’s post-Brexit partnership with the European Union, avowedly backed Kyiv and thawed ties with China. At a time of geopolitical upheaval, he is attempting to squeeze Britain into an impossibly tight Venn diagram.

Prime Minister Keir Starmer of Britain cut international aid to raise military spending. He’s hoping to make a case for Ukraine at the White House.

Starmer's sought a U.S. commitment to “backstop” European peacekeeping in Ukraine in the event of a ceasefire with Russia, which Trump avoided.
