This document discusses ballistic missile defense systems in East Asia. It defines missiles and ballistic missiles, and describes the types of missiles. It then outlines the key missile defense systems used by South Korea and Japan, including THAAD, Patriot PAC-3, Aegis ships, and early warning radars. Finally, it lists some merits of missile defense systems as providing security, avoiding retaliation, and saving lives, while acknowledging the demerits are the high cost and risk of technology theft.
