US deploys MORE Patriot missiles in South Korea in response to North Korea’s nuclear test .

North Korea is really a threat to South Korea and the World at large. Recently they launched a nuclear test which as a result endangers South Korea and other countries surrounding them.

But the United States temporarily deployed an additional Patriot missile battery in South Korea in response to North Korea's nuclear test and a long-range rocket launch, ahead of talks next week to set up an even more sophisticated U.S. missile defense in a move that has worried China and Russia.

The new tough stance follows South Korea’s decision to shut down an inter-Korean factory park that had been the rival Koreas’ last major symbol of cooperation, but that Seoul said had been used by North Korea to fund its nuclear and missile programs.

North Korea responded by deporting South Korean citizens, seizing South Korean assets and vowing to militarize the park.

South Korea on Friday cut off power and water supplies to the industrial park and announced that its planned talks with the United States on deploying the Terminal High-Altitude Area Defense, or THAAD, one of the most advanced missile defense systems in the world, could start next week. Officials say they have yet to set a specific starting date for the talks.

In the meantime, the U.S. military command in South Korea said Saturday that an air defense battery unit from Ft. Bliss, Texas, has been conducting ballistic missile training using the Patriot system at Osan Air Base near Seoul.

Lt. Gen. Thomas Vandal, commander of the U.S. Eighth Army, said ‘exercises like this ensure we are always ready to defend against an attack from North Korea.’

‘North Korea’s continued development of ballistic missiles against the expressed will of the international community requires the alliance to maintain effective and ready ballistic missile defenses,’ he said in a statement.

A spokeswoman for U.S. Forces Korea couldn’t confirm how long the Patriot missile battery from Texas would be deployed in South Korea. The U.S. military already has an operating Patriot missile defense system in South Korea to counter the threat of North Korea’s shorter-range arsenal and medium-range missiles.
