Abstract
The U.S. deployed a missile defense system, Terminal High Altitude Area Defense (THAAD) in South Korea in April 2017, citing North Korea’s nuclear and missile “threats” as justification. Its deployment, however, needs to be seen in the wider strategic context. Not only does the measure raise the arms race with North Korea, it also facilitates Japan’s “proactive contribution to peace” and exacerbates the security dilemma between the U.S. and its allies on one side and China and Russia on the other.
