North Korea has apparently carried out another nuclear test Feb. 12, days after suggesting the West was mistaken that such an event would occur soon. Like the recent missile launch, the North has again sought to catch observers off guard even as everyone expected a nuclear test.
In the lead-up to the Unha-3 launch, Pyongyang moved the launch window and made it appear to satellites that it was removing its rocket from the launch pad. Just before the current nuclear test, Pyongyang toned down its public test warnings (though it apparently sent last-minute warnings to Washington and Beijing). The pattern is part of Pyongyang's attempts to keep potential observers guessing. However, despite some Western media taking North Korea's latest statement at face value, the South Korean government and media continued to caution that Pyongyang was likely to test this week.
It is not clear yet what sort of device North Korea tested. Initial estimates suggest a six- to seven-kiloton yield, which is slightly larger than past North Korean tests. Prior to the test, it was suspected that the North would test a uranium device as a follow-on to its two earlier plutonium tests. This would mark another step in North Korea's nuclear program, though North Korea has long been known to be working on a secondary uranium program, and in some ways a nuclear reaction with uranium is technically easier to effectively detonate than a plutonium reaction. It also could be a third plutonium test, as North Korea continues to refine its nuclear program and work toward a viable nuclear weapon, as opposed to just a nuclear device. Follow-up analysis of the seismic signature and air samples from over the site will offer additional information about the test in coming weeks.
Although Pyongyang has pursued a strategy of survival based on presenting a fearsome, irrational, yet weak image, the North is also pursuing its nuclear and missile program as more than just a bargaining chip. Pyongyang truly wants to move forward with what it considers a viable deterrent, a weaponized nuclear device that can fit on a missile. This would not be to keep its neighbors at bay (as they are close enough for north Korea's conventional weapons), but to offer the North an independent deterrent in relation to the United States. A small number of nuclear missiles is not a significant threat to the United States, but Pyongyang sees it as a way of removing its dependence on China and as a strategic deterrence toward Washington. The North does not always agree with Beijing, and it is concerned that it has grown too dependent upon China. Pyongyang has sought an independent deterrent in order to feel confident enough to either open direct talks with the United States to end the state of armistice in place since 1953, or to simply move forward with some elements of domestic economic experiments, more confident that it can dissuade U.S. interference.
By keeping the program seemingly viable but ambiguous (underground tests, space launches, but no proof of weaponized nuclear warheads and effective long-range ballistic missile guidance systems), Pyongyang is seeking a deterrence without forcing a military pre-emption. Although there will be a loud outcry from the international community, and additional sanctions on North Korea, nuclear testing and rocket launches are becoming routine for North Korea, which is perhaps exactly what North Korea wants.
