Not conducive to South Korea's national defense security: the north-south length of the Korean Peninsula is not long, so if North Korea really wants to attack South Korea, it will choose short-range missiles instead of long-range missiles, and "Sade" as the terminal high-altitude regional defense system cannot intercept short-range missiles;
Reasons for instability in South Korea: At present, on the issue of "Sade", the division of Korean society is still relatively serious, and the voices of opposition mainly exist in the opposition parties, local governments and some people and scholars in South Korea. For them, the deployment of the "Sade" system can not only protect national security, but also lead to South Korea's involvement in the big country game;
Geopolitically, South Korea is isolated: before this issue, China-South Korea relations were very good and South Korea benefited a lot. As soon as the "Sade" decision came out, China-ROK relations suddenly cooled down in many aspects, and mutual trust between the two countries was seriously damaged.
The Saad anti-missile system is introduced as follows:
THAAD Sadr anti-missile system, also known as terminal high altitude area defense, is a land-based theater anti-missile system under the US Missile Defense Agency and the US Army.
The predecessor of this system is the theater high-altitude area defense system, which ended in many failures. In 2004, the US Army redesigned the system and renamed it its current name. The system consists of command system, interception system, launch system, radar and its supporting equipment.
Its purpose is not to replace but to supplement the MIM- 104 air defense missile, the Navy Aegis ballistic missile defense system, the land-based midcourse defense system, and the early warning radar and sensors deployed by the United States around the world, so that the US military has multi-layer ballistic missile defense capabilities and is a strategic offensive weapon.
On July 8, 20 16, the United States and South Korea officially announced that they would deploy the Sadr anti-missile system in South Korea, which caused great controversy in South Korea and strong dissatisfaction among regional countries.
