NATO's biggest summit of the year was a win for the U.S. President, who secured the pledges of dramatically increased defense spending he has long demanded.

U.S. President Donald Trump on Wednesday wrapped up participation in the annual NATO summit, a gathering notable this year for an atmosphere that was far chummier toward Trump than the tension-filled meetings of his first term.

In a press conference before heading back to Washington, Trump struck a conciliatory tone as he sought to harvest praise for the spending boost.
