Lil Kim is stepping up the threat with a warning of a nuclear strike in the coming days. ""The moment of explosion is approaching fast," the North Korean military said, warning that war could break out "today or tomorrow". Pyongyang's latest pronouncement came as Washington scrambled to reinforce its Pacific missile defences, preparing to send ground-based interceptors to Guam and dispatching two Aegis class destroyers to the region. Tension was also high on the North's heavily fortified border with South Korea, after Kim Jong-Un's isolated regime barred South Koreans from entering a Seoul-funded joint industrial park on its side of the frontier. In a statement published by the state KCNA news agency, the Korean People's Army general staff warned Washington that US threats would be "smashed by... cutting-edge smaller, lighter and diversified nuclear strike means". "The merciless operation of our revolutionary armed forces in this regard has been finally examined and ratified," the statement said. Last month, North Korea threatened a "pre-emptive" nuclear strike against the United States, and last week its supreme army command ordered strategic rocket units to combat status. But, while Pyongyang has successfully carried out test nuclear detonations, most experts think it is not yet capable of mounting a device on a ballistic missile capable of striking US bases or territory. Mounting tension in the region could however trigger incidents on the tense and heavily militarised border between North and South Korea. The White House was swift to react to Pyongyang's latest "unhelpful and unconstructive threats". National Security Council spokeswoman Caitlin Hayden said: "It is yet another offering in a long line of provocative statements that only serve to further isolate North Korea from the rest of the international community and undermine its goal of economic development. "North Korea should stop its provocative threats and instead concentrate on abiding by its international obligations." US Defense Secretary Chuck Hagel earlier said Pyongyang represented a "real and clear danger" to the United States and to its allies South Korea and Japan. "They have nuclear capacity now, they have missile delivery capacity now," Hagel said after a strategy speech at the National Defense University. "We take those threats seriously, we have to take those threats seriously." Full article:http://news.xin.msn.com/en/world/n-korea-approves-nuclear-strike-on-united-states-1 Thoughts? Is Lil Kim finally playing his hand or is this more saber rattling? Would they even get the chance to launch and if so could they survive the retaliation from the US? If anyone is crazy enough to poke the sleeping giant it's NK. Pictures leaked last week showed US targets in Hawaii California, Washington DC and Austin. Anyone rewatch Red Dawn lately?
