Always vigilant, always ready
Matt Drudge is reporting that U.S. spy satellites have spotted heightened activity at missile sites and other "suspect sites" in North Korea. So the ever-vigilant U.S. has quietly warned China that North Korea could be preparing for a nuclear-weapons test and asked the Chinese to urge Pyongyang to desist. Fears of these tests have also been conveyed, Drudge reports, to South Korea and Japan.
Meanwhile, the U.S., the only nation in history to use nuclear weapons against civilian populations, keeps its arsenal ready for anything.
