The politicians aren't the only ones stepping up their opposition against a third nuclear test.

Chairman of the Joint Chiefs of Staff, General Jung Seung-jo on Wednesday hinted that the South Korean military may launch a pre-emptive strike against North Korea, if Pyongyang shows a clear intent to use nuclear weapons on the South-- this, even at the risk of full-scale war.

The general added that it might be safer for South Korea to act pre-emptively rather than after an actual attack.

As to whether the military has plans to destroy North Korea's's nuclear test sites Jung said he would make that decision according to the circumstances.
