In a fiery speech before the UN General Assembly on Saturday, North Korean Foreign Minister Ri Yong Ho heavily criticized President Donald Trump and vowed that his country could take “preemptive action” against the United States.

Without specifying what kind of action was being contemplated, Ri said, “We will take preventive measures by merciless pre-emptive action in case the U.S. and its vassal forces show any sign of conducting a kind of ‘decapitating’ operation on our headquarters or military attack against our country.” That was a reference to earlier reporting that South Korea is forming a special unit aimed at taking out North Korean leadership as an adjunct to U.S. decapitation plans.

“However, we do not have any intention at all to use or threaten to use nuclear weapons against the countries that do not join in the U.S. military actions against the DPRK,” he added, using the acronym for the North’s formal name, the Democratic People’s Republic of Korea.

“Our national nuclear force is, to all intents and purposes, a war deterrent for putting an end to nuclear threat of the U.S. and for preventing its military invasion, and our ultimate goal is to establish the balance of power with the U.S.,” Ri said.

Actions could be anything from setting off another nuclear explosion in the Pacific Ocean, as has been threatened, to direct military attack on U.S., South Korean, or Japanese forces.
