Taking Preemptive Action Against North Korea

"In light of North Korea's nuclear test, the United States and South Korea have agreed to develop a new contingency plan to take military action against North Korea in scenarios short of North Korea attack or in response to a catastrophic "collapse" in the North.

The new revised plan - CONPLAN 5029 -focuses on preemptive action to thwart North Korean moves involving potential export of weapons of mass destruction.

Pentagon sources confirm that the new plan will be the first joint U.S.-South Korean plan to take action against North Korea even if the North does not invade or attack the South first." More.
