Thus far, North Korea has been all bark and no bite. After their aggressive announcement Saturday that they’re entering a “state of war” with South Korea, their southern neighbor is hoping it stays that way. North Korea’s threat is the latest in a string of warnings it has issued since February, many threatening nuclear warfare against the United States. Despite the frequency of the threats and the unlikelihood of their coming to fruition, U.S. officials have been taking them seriously. "The long-standing situation of the Korean peninsula being neither at peace nor at war is finally over," reads the announcement. But the announcement's wrong: North and South Korea have technically been at war since 1953, as the armistice that ended the Korean War was never turned into a treaty.
