Critics Say U.S. Is 'Sleepwalking' Into Wider Role in Syria

Russia has retaliated by threatening to treat American planes as targets; in a dramatic "Top Gun"-style maneuver on Monday, one of Moscow's jets buzzed within five feet of an American spy plane. None of these encounters involved the Islamic State. The contradiction opens a larger question, national security experts say, of what kind of broader strategy the Trump administration plans once the Islamic State -- now on the defensive -- is defeated in Syria. With each episode, "we own more of the conflict in Syria without articulating a strategy," said Vali Nasr, dean of the Johns Hopkins School of Advanced International Studies. "We are sleepwalking into a much broader military mandate, without saying what we plan to do afterward."
