President Trump has decided to quickly withdraw all U.S. troops from Syria, against the advice of his most senior national security advisers. The move prompted the resignation of Secretary of Defense James Mattis and sparked widespread concerns about an ISIS revival.
The big picture: Aside from the results of the decision, the manner in which Trump made it was deeply problematic. By upending the public and private messages his own officials send, Trump disempowers and alienates his own diplomatic team. He also creates incentives that make his foreign policy agenda more difficult to attain.
