NATO has weathered another ?storm from Donald Trump but European members of the military alliance are bracing for more turbulence ahead in relations with the U.S. president.

It says much about the state of U.S.-European ties when a NATO summit that began with a U.S. leader ordering a cutoff in trade with one member, Spain, and rebuking others was widely hailed as a success after he recommitted to the alliance hours later.

European leaders were upbeat after the Ankara summit, pleased by Trump¡¯s talk of ¡°love in the room,¡± his endorsement of a declaration that reiterated support for NATO¡¯s Article 5 mutual defense pact ?and his decision to give Ukraine a license to make Patriot missile interceptors.
