In vowing to pull thousands of U.S. troops from Germany, President Donald Trump is following a pattern of disruptive moves against allies that have dismayed many of his fellow Republicans. Trump has consistently promised to bring American troops home, dismissing the conventional view that a far-flung U.S. military presence, while costly, pays off in the long run by ensuring stability for global trade. Earlier this week he said the 34,500 U.S. troops in Germany would be reduced to 25,000. (AP Photo/Markus Schreiber, File)
