After the United States flew two nuclear-capable B-2 bombers over South Korea as part of its war games with that country, the North announced it had put its missiles on standby to attack U.S. and South Korean targets for real. But while the Korean Central News Agency reports the missiles are trained on the U.S. mainland and bases in the Pacific, the only working missiles we know the North has are short-range Soviet-era Scuds, which can only reach South Korea. “Its longer-range Nodong and Musudan missiles that could in theory hit U.S. Pacific bases are untested,” Reuters reports. Meanwhile, soldiers and students marched in a big anti-U.S. rally in Pyongyang. Nobody really believes North Korea will attack the U.S., but it’s been known to open fire locally from time to time, so this is still worrisome.
