North Korea has released warnings against the South Korea over the weekend. The North Korean military announced this news by using extreme words: "turning Seoul into a sea fire." They have threatened South Korea with their nuclear missile powers. Shockingly, North has consistently announced the defensive movement as a preparation for another war on the Korean Peninsula, and it has repeated again.
Once in 1960, and a second threat in 2004, which this year, 2011, counts as their third time. North Korea has announced that they will blow up imjingank, a river near seoul. South  should keep its armed forces on full alert against renewed military threats from the North, while being ready to calm down Pyongyang with a peaceful approach. This threats have been scaring the South Korea citiziens due to North Korea's powerful nuclear weapon that has been fully armed over many years. I believe that both South and North soon needs to have meeting over severe threats in order to calm down peoples' worries, which definetely can lead both countries in war.
