In July 2019, Turkey began receiving shipments of an advanced missile system from a Russian entity on a sanctions list kept by the U.S. Secretary of State. The creation of this list was mandated by a law enacted by the U.S. Congress to isolate Russia, Iran, and North Korea.  Turkey should face sanctions, and if the President is seen as soft in imposing them, Congress may intercede.  Turkey, and other states, are watching the U.S. reaction, and will determine future policies with it in mind.
