The Aegis Ballistic Missile Defense System

Building an interoperable missile defense system is a key focus the United States places on trilateral cooperation with its two key Asian allies, South Korea and Japan, a senior American diplomat said.
Principal Deputy Assistant Secretary of State Anita Friedt made the remark at the Japan Institute of International Affairs in Tokyo earlier Friday, echoing what Assistant Secretary Frank Rose said during a recent trip to Seoul, according to the State Department.
