BRUSSELS (Reuters) - Key allies of Washington expressed concern on Friday about the resignation of U.S. Defense Secretary Jim Mattis and the policies of President Donald Trump that prompted it, praising Mattis as a committed partner.
Mattis said on Thursday he would quit after falling out with Trump over the latter's foreign policies, including the surprise decision to pull troops out of Syria and plans for a drawdown in Afghanistan.
