Turkey's Presidential Runoff and Its Implications for US, NATO, and Trade.

The first-ever presidential runoff election in Turkey will be decided Sunday, and two competing visions for the important NATO-member country will affect relations between Ankara and Washington. The current strongman, Turkish President Recep Tayyip Erdogan, known for his brand of populist political Islam, squares off against his social democratic Republic People’s Party challenger, Kemal Kilicdaroglu. The margin of an Erdogan victory will likely determine Erdogan’s reaction to the US. Turkey’s foreign policy is mired in an occupation of northern Syria and repeated attacks against Kurdish forces who fought with the US to oust the Islamic State. The US Congress has blocked sales of F-16 fighter jets to Turkey until Erdogan ratifies NATO membership for Sweden and Finland.
