Some speculate that this is simply preparations to
test the country's nuclear capabilities. This announcement came shortly after Kim had a emergency conference with his top defense and security officials. The country has been officially under a state of martial law since mid-night January 29th. The last time North Korea was under
martial law was in 1993, just before the country withdrew from the non-proliferation of nuclear weapons treaty.
Analysts aren't surprise at the actions taken by the North Korean government. The birthday celebration of the late Kim Jong-il takes place on Feb 16; which leads analysts to think this might be the reason why the country is moving forward with the nuclear tests.
South Korean president, Lee Myung-bak, has already begun making preparations, ordering the military to be prepared for the worst; just in case that North Korea provokes an action against South Korea.
