The right choice is equipping the Kurds with what they need to win in Raqqa. Trump probably does need at least the tacit acquiescence of Ankara. Yes, that's a hard sell: Turkish President Recep Tayyip Erdogan continues to veer his country, a NATO member nation, away from the West and into the orbit of Russian President Vladimir Putin. In the fight against Islamic State, the Kremlin has hardly been a help. Putin paints the Islamic State as an enemy to be eradicated, but almost every move he makes in Syria is about keeping Bashar Assad's regime in power. Russia has largely left the task of Raqqa to U.S.-backed Syrian Democratic Forces.
