Turkey Continues to Address Issues with Russian S-400 Missile System

President Erdogan's team in Turkey is working on issues related to the Russian S-400 missile system, which hampers the country's return to the F-35 fighter jet program. The Turkish Ministry of Defense stated that multidimensional work continues on the S-400 system, but specifics have yet to be revealed. The U.S. Congress has passed a law banning the sale of F-35 jets until Turkey relinquishes its S-400 system.
