The tensions on the Korean peninsula is mounting as a result of North Korea's deadly attack near Baeknyeong island in the West Sea on the South Korean patrol ship Cheonan in March 26. 2010 and the bombardment to a private citizen's place of residence at Yeonphyeong Island on November 23, 2010. Cheonan ship incident reminds our people and three neighbors(S.Korea,
Japan, China) that North Korea can also impede regional cooperation by causing security problems. President Lee Myung-bak proclaimed officially and internationally that the sinking incident of Cheonan ship is the provocation of North Korea to attack on South Korea on May 24. 2010. North Korea has committed continuous attempts of the military provocation and maneuver to break South Korea without hesitation. An unexpected and periodical repetition of
provocation is not only to grasp an alert of korean combat unit but also to check an ability of risk management, including the countermeasures, rationality and agility of the high- level military policy making process. On the other hand, the provocation of North Korea has a tactical intention on the national sychological level and terrorism to South Korea. If North Korea abandon or cease the violent struggle, they know to weaken the hostility to South Korea, also is to raise the level of provocation and maneuver in order to get over the difficulties of a violent revolution.
