On October 9, 2006, North Korea conducted its first nuclear test. Since then, the nation has tested nuclear devices four more times, most recently in September 2016. Running parallel and complementary to the nuclear program is a missile program that, twice in July, tested ICBMs with a range that can likely reach most of the continental United States. Earlier this week, a report from the Defense Intelligence Agency estimated that North Korea has miniaturized a nuclear warhead, making it small enough to fit on a missile.
