Who can trust Trump's America?

摘要

The pithiest summary of Donald Trump's foreign policy comes from the president himself. Referring to the mayhem he has uncorked in Syria, he tweeted: "i hope they all do great, we are 7,000 miles away!" Mr Trump imagines he can abandon an ally in a dangerous region without serious consequences for the United States. He is wrong. The betrayal of the Kurds will lead friends and foes to doubt Mr Trump's America. That is something both Americans and the world should lament.
