North Korea is pledging to revive its nuclear enrichment program that it said previously didn't exist. This tantrum is in response to sanctions leveled against Kim's regime by the UN Security Council for detonating a second nuclear bomb.

Blaine Harden of the Washington Post:

"It makes no difference to North Korea whether its nuclear status is recognized or not," the Foreign Ministry in Pyongyang said in a statement carried by the state news agency. "It has become an absolutely impossible option for North Korea to even think about giving up its nuclear weapons."

The 15-member Security Council unanimously passed a resolution Friday that imposes broad financial, trade and military sanctions on North Korea, while also calling on states, for the first time, to seize banned weapons and technology from the North that are found aboard ships on the high seas. North Korea seemed Saturday to have interpreted the seizure resolution as a "blockade." But at the insistence of China and Russia, the North's traditional allies, the resolution does not authorize the use of military action to enforce any seizure that a North Korean vessel might resist, nor does it restrict shipments of food or other nonmilitary goods.

"An attempted blockade of any kind by the United States and its followers will be regarded as an act of war and met with a decisive military response," North Korea said.

Secretary of State Hillary Rodham Clinton said North Korea's "continuing provocative actions are deeply regrettable."
