North Korea's state-run media reported Sunday that North Korean leader Kim Jong Un has ordered the country's top security officials to take "substantial and high-profile important state measures," which has been widely interpreted to mean that North Korea is planning its third nuclear test. Kim said the orders were retaliation for the U.S.-led push to tighten U.N. sanctions on Pyongyang following North Korea's missile test in October. A few days before Kim's statement emerged, the North Koreans said future tests would target the United States, which North Korea regards as its key adversary along with Washington's tool, South Korea.
North Korea has been using the threat of tests and the tests themselves as weapons against its neighbors and the United States for years. On the surface, threatening to test weapons does not appear particularly sensible. If the test fails, you look weak. If it succeeds, you look dangerous without actually having a deliverable weapon. And the closer you come to having a weapon, the more likely someone is to attack you so you don't succeed in actually getting one. Developing a weapon in absolute secret would seem to make more sense. When the weapon is ready, you display it, and you have something solid to threaten enemies with.
