Stephen Walt: From Israel to Iran to Mexico, Trump Has Already Blown It on Foreign Policy

We turn now to look at President Trump's emerging foreign policy. Last week, Trump reportedly abruptly ended a call with Australian Prime Minister Malcolm Turnbull after complaining about the terms of a refugee deal between the U.S. and Australia. Meanwhile, during a call with Mexican President Enrique Pena Nieto, Trump reportedly threatened to send U.S. troops to Mexico. Trump's national security adviser, Michael Flynn, also announced the United States was putting Iran "on notice"-but it's not clear what that means. And Trump's first covert operation in Yemen went disastrously wrong: One U.S. Navy SEAL and as many as 23 Yemeni civilians died as a result. We speak to Harvard professor Stephen Walt. His recent piece in Foreign Policy is headlined "Trump Has Already Blown It."
