Cold War 2.0
The joint decision of Washington and Seoul to deploy the U.S. Terminal High Altitude Air Defense (THAAD) system in South Korea damages the mutual trust and cooperation developed with China by threatening China's strategic security interests.
The move, regardless of China's repeated opposition, undermines the foundation of their strategic cooperative partnership at a time when it actually should be deepening.
The decision to deploy THAAD breaks the regional strategic balance by tying South Korea to the U.S. chariot of Asia-Pacific re-balancing.
With the system's X-band radar commanding surveillance of an area that extends over 1,200 miles (about 1,900 km) from the Korean Peninsula, the United States can spy on almost half of China's territory and the southern part of Russia's Far East, endangering the two countries' national security.
Such a system challenges Seoul's argument that it is only directed at missile and nuclear threats alleged from the Democratic People's Republic of Korea (DPRK). As it fits well into Washington's planned anti-missile shield against China in the Asia-Pacific, some South Korean media have commented it as a result of humiliated diplomacy and a move to serve U.S. Hegemony.
