"As global challenges to U.S. interests have changed over time, U.S. relations with Turkey--an important ally since the Cold War era--have evolved. Congress appropriates relatively small amounts of military and security assistance for Turkey compared with past sums, but still plays an active role in shaping and overseeing U.S. relations with Turkey. Several Turkish domestic and foreign policy issues have significant relevance for U.S. interests. U.S. policymakers are closely observing the domestic unrest that began in late May 2013 and spread across Turkey in June to determine how it may impact U.S. interests (see 'June 2013 Protests and Their Implications' below). Gauging how U.S. and Turkish interests coincide has become increasingly complicated and dynamic."
