Ex-US defence chief: European allies 'unsure' about US relationship
President Donald Trump's statements, both as a candidate and as president, have at times alarmed US allies in Europe.
Former US Defence Secretary and BBC World Affairs Analyst William Cohen, just returned from the Munich Security Conference, where he says America's European allies have expressed concerns about US commitment to their region.
"They are unsure and they are worried about whether or not we are strongly not only in favor of Nato, but also the EU," he told the BBC's Laura Trevelyan.
