Yesterday, the White House released the readout of a call between President Donald Trump and the King of Saudi Arabia, Salman bin Abdulaziz al Saud. The statement featured this remarkable statement: “The President requested and the King agreed to support safe zones in Syria and Yemen, as well as supporting other ideas to help the many refugees who are displaced by the ongoing conflicts.”

During the presidential campaign, Trump, as well as Mike Pence, repeatedly endorsed the creation of safe zones in Syria, without adding any clarification. Trump proclaimed that unnamed Middle East countries would pay for the “big, beautiful safe zone” in Syria, while Pence during the vice presidential debate proclaimed they would “create a route for safe passage” and “protect people in those areas, including with the no-fly zone.” Five days later, when asked about his running mate’s position Trump declared flatly: “He and I haven’t spoken, and I disagree.”

Political campaigns are consequence-free environments, but statements made while serving as chief of state should reflect actual government policy. If President Trump is now serious about authorizing the U.S. armed forces to implement safe zones (as indicated by his request to the Saudi monarch), he and his senior aides must clarify exactly what he means by this new, expansive, and poorly conceived military mission.
