Franz-Stefan Gady, senior fellow at the Eastwest Institute, spoke on This Morning with Alex Jensen (tbs eFM 101.3 MHz) in Seoul about the new Russian S-400 air defense system.

"One of the most effective long-range air defense systems in the world", said Gady. He compared the S-400 with the U.S. THAAD system and discussed the global sale of these air defense systems in Turkey, China, Greece, India and South Korea.

According to Gady, "the S-400 is not really a threat to U.S. ballistic missiles . . . given that they are all stationed in the continental U.S. or on submarines or bombers," however "these weapons . . . would be used to shoot down U.S. aircraft or allied aircraft and missiles" in the event of a conflict between the U.S. and Russia or China.
