Trump campaigned on the promise of not getting involved in foreign conflicts. During the campaign, Trump called the war in Iraq a disaster (even though he supported it at the time) and blamed Hillary Clinton for the chaos in the Middle East. He criticized her for the decision to topple Gaddafi in Libya (guess what – he supported that too.) In his first major speech on foreign policy since the election, Trump introduced Mattis as his defense pick and laid out his vision for a new era of U.S. foreign policy.
