Hardliners have taken over the Russian government - democracy in Russia is dead and the Cold War has been restarted. In response Jon Vauclain and Kerry Enloe have invented the perfect missile defense system, knowing that if it is used, the system will stop everything entering U.S. airspace, including commercial aircraft.
