The plan would "contain" major US military bases on the island, including Anderson Air Force Base, the spokesman said, where B-1 strategic bombers go to refuel after flying missions over South Korea. The strategic bombers "get on the nerves of the DPRK and threaten and blackmail it through their frequent visits to the sky above South Korea," the statement said.
Earlier in the day, Trump thundered that it was best for Pyongyang "not to make any more threats to the US" seeing that any escalation of such threats would be "met with the fires and fury and, frankly, power, the likes of which this world has never seen before."
North Korea "appears to have… demonstrated an intermediate-range ballistic missile that might enable them to reliably strike the US base at Guam," rocket specialist John Schilling of 38 North wrote in May.
"The plan is soon to be reported to the Supreme Command," North Korea's Strategic Force noted in the statement. After contemplation by Supreme Leader Kim Jong-un, the plan will "be put into practice in a multi-concurrent and consecutive way any moment once" Kim makes a decision.
On Saturday, the United Nations Security Council unanimously passed the toughest economic sanctions to date against North Korea, intended to slash $1 billion from the isolated nation's roughly $3 billion in export revenue. In response, North Korea pledged to take decisive steps, including "physical actions."
Korean People's Army Officer Sin Kwang-jin told KCNA, "the US is getting more impatient for the DPRK's nuclear deterrent, but it cannot be construed otherwise than its recognition of the victory won by the DPRK," adding that it's erroneous for the US to think that "sanction is almighty."
"Our nuclear weapons of justice will mercilessly hammer the nuclear of tyranny," Sin said.
North Korea tested two ballistic missiles last month, believed by many to be intercontinental ballistic missiles capable of reaching the US mainland. The country has also continued testing nuclear weapons despite international sanctions. On Tuesday, it was revealed that both US and Japanese intelligence agencies believe Pyongyang has achieved its goal of developing nuclear capable intercontinental ballistic missiles.
