THAADミサイル
The United States placed a Terminal High Altitude Area Defense(THAAD) in South Korea to protect the country from missile strikes from the North. This defense system is capable of intercepting Ballistic missiles of all ranges. The missile defense system coupled with the plan of a massive retaliatory strike has given South Korea a better sense of security against the North. The threat of a massive retaliation from the South was a deterrent for the North.
