The US Forces Korea (USFK) announced the deployment of the Terminal High Altitude Area Defence (THAAD) system is a “tentative” attempt to foil any spontaneous plots from despot leader Kim Jong-un.
The USFK said: "THAAD intercepts short and medium range ballistic missiles inside and outside the atmosphere.
"It is interoperable with other ballistic missile defence systems, highly mobile, and deployable worldwide."
The system, that was announced last month, can identify incoming missiles “at ranges up to 1,000 km [621miles]”.The range of the THAAD system allows North Korea and some parts of China to be scoured for potential threats.
Beijing has voiced intense opposition to the radar technology due to a spying risk.
However, military experts have attempted to extinguish China’s complaints by stating that the optimal range of the system is 372miles (600km) to 497 miles (800km)

The THAAD system in South Korea will be used to monitor the dangerous isolationist state and is capable of shooting down ballistic missiles at altitudes of 24miles (40km) to 93 miles (150km).
A defence system is seemingly a necessity with the world seemingly on the brink of World War Three.
