The harsh rhetoric by North Korea's People's Army (KPA) is the communist state's first comment on Terminal High Altitude Area Defense (THAAD) since the U.S. and South Korea announced Friday they are in the final stages of negotiation about where to deploy the missile system.
THAAD can shoot down short, medium and intermediate ballistic missiles at incredible speed and altitude, and has been used by the U.S. for years to protect its military units.
