The reason I called the president Donald Trump a disrupter is that he came into office 70 years after World War II, 25-plus years after the end of the Cold War. Like any president, he didn't come into office with a blank slate - he entered with an enormous inheritance of relationships with institutions, policies and the like. And in my view he is much too quick to pull the U.S. out of various institutions and various agreements, and he's been much too quick to question the value of allies and alliances.
