N. Korea Threatens to Attack U.S.

The drills may be "just a test," but North Korea doesn't seem to care. After South Korea and the U.S. began their annual drills—which include computer war games and live-firing exercises, among other training—North Korea accused the countries of launching a "dangerous" plot to overthrow it, and vowed retribution on the allies. In a statement, the rogue nation threatened to launch a "full-scare" war with counterattacks. Meanwhile, the South Korean and U.S. militaries say they're simply practicing for any potential emergency in the area.
