NATO to Try ‘Kitchen Table’ to Soothe U.S.-Turkey Dispute

BRUSSELS—Western diplomats hope to use a high-level gathering of the North Atlantic Treaty Organization this week to keep members U.S. and Turkey from going to battle against each other in Syria.

They have already come close to direct conflict. Turkey, angered by U.S. support for Syrian Kurdish militants whom Ankara considers terrorists, has been fighting Kurds in one Syrian town and threatened to go after them in another—where several hundred U.S. Special Forces are deployed.
