After European leaders stepped up military spending, President Trump aligned himself more closely with them on the war. But his tariffs threats have left bruises.

Several European countries said on Tuesday they were willing to buy U.S. arms for Ukraine under a scheme announced by U.S. President Donald Trump, although arrangements still needed to be worked out.

U.S. President Donald Trump said he believed Britain would fight to defend the United States but suggested he could not say the same for the European Union, a factor in his decision not to sign a trade deal with the bloc.
