US Calls Out Turkey, Slams Syrian Incursion as 'Very Big Mistake' Margaret Besheer UNITED NATIONS - U.S. diplomats are pushing back on Turkey's incursion into northeastern Syria, labeling the military maneuver a "very big mistake" that could have significant consequences on the security situation in the region and beyond. The criticism from Washington, echoed by European officials and members of the United Nation's Security Council, came as Turkish artillery and war planes pounded Kurdish positions on the Syrian side of the border for a second straight day Thursday, forcing thousands of civilians to flee. Turkey, in a letter to the United Nations, said its response would be "proportionate, measured and responsible." But top U.S. officials warned that even if Ankara can make good on such assurances, the consequences of its incursion into Syria are dire. .
