Turkish troops and armored units are massed along Turkey’s southern border awaiting orders to invade northern Syria. Turkish President Recep Tayyip Erdogan wants to clear a ten mile-deep swath of land east of the Euphrates River in order to remove terrorist-linked militants (YPG) currently occupying the territory. The proposed offensive would put US Special Forces in the line of fire which significantly increases the likelihood of US casualties. If American troops are killed or wounded by the Turkish operation, Washington will respond in force leading to a potentially catastrophic face-off between the two NATO allies. The possibility of a violent clash between Turkey and the United States has never been greater than it is today.
