This is a high-stakes gamble. It’s in the U.S. interest to make sure Islamic State terrorists never return to the battlefield. The White House message may well be meant for Erdogan, warning him against a large-scale campaign against the Kurdish positions. Turkey lacks the resources and capabilities to detain those fighters.
One problem with all this, of course, is Trump himself — specifically, the way he has decided to portray the crisis in northern Syria as part of his campaign to end “endless wars.” In January, after Trump backtracked from an earlier promise to withdraw from Syria, he threatened Turkey with “economic devastation” if Erdogan attacked America’s Kurdish allies. This time around, Trump has announced on Twitter that he “will totally destroy and obliterate the Economy of Turkey” if it “does anything that I, in my great and unmatched wisdom, consider to be off limits.”
