The apocalyptic pronouncements from Pyongyang have a silver lining: They may be motivating the world to take unprecedented action against the North.
The White House will have ample opportunity to talk up this solidarity this week as South Korean President Lee Myung-bak travels to Washington for talks expected to focus on the North's nuclear and missile programs.
For its part, Pyongyang over the weekend threatened war with any nation that stops North Korean ships on the high seas and attempts to inspect them for illicit nuclear or weapons shipments. Such inspections would be allowed under the terms of the UN Security Council resolution.
North Korea also vowed to turn into weapons-usable material its small stockpile of plutonium and acknowledged that it has a uranium enrichment program, as the US has long suspected.
