For the first time in 70 years, the American people have elected a president who disparages the policies, ideas, and institutions at the heart of postwar U.S. foreign policy. No one knows how the foreign policy of the Trump administration will take shape, or how the new president’s priorities and preferences will shift as he encounters the torrent of events and crises ahead.
