The handwriting was on the wall and now the ongoing flap between the United States and Turkey over the U.S threatening to impose sanctions on Ankara, for buying a Russian missile system, is reaching a tipping point.

Turkish President Recep Tayyip Erdogan threatened to close two strategic U.S. airbases at Incirlik and Kurecik over these sanctions. 

“If necessary, we’ll close Incirlik and also Kurecik,” Erdogan said on Sunday. “If the threat of sanctions is implemented against us, we’ll respond to them in the framework of reciprocity.”

Turkish Foreign Minister Mevlut Cavusoglu also brought up U.S. base closure last week when the threat of sanctions was brought up by Washington. He stated that the base closure would “be put on the table.”
