North Korean nuclear crisis
There are almost 18,000 nuclear warheads distributed among nine nuclear-armed states in the world today. Over 90 percent of these are in Russian and U.S. arsenals. But concerns about the growth in nuclear weapons stockpiles are focused on China, India, North
Korea and Pakistan.
North Korea is estimated to have four to 10 nuclear warheads — the smallest arsenal of all — and remains the subject of intense diplomatic efforts aimed at reversing its nuclear status. Its nuclear and missile programs are a source of instability and tension in a region vital to global security and economic prosperity.
Having withdrawn from the NPT in 2003, Pyongyang has repeatedly made commitments to abandon the weapons path in return for security assurances and economic assistance, shelved its nuclear ambitions temporarily, and then broken its promises serially.
Its 2006 and 2009, nuclear tests drew international condemnations and U.N.-mandated sanctions, prompting it to walk out of the six-party talks. Security Council Resolution 1874
(June 12, 2009) prohibited further tests or launches using ballistic missile technology, and toughened the sanctions. After initial failure in April 2012, a long-range rocket was successfully launched on Dec. 12. Japanese experts were impressed by the precision of the rocket technology and by the fact that the test was planned for and executed during adverse winter conditions.
Many condemned the launch as a disguised ballistic missile test forbidden by U.N. resolutions. This was followed by a third nuclear test Feb. 12.
Nuclear weapons can be made from highly enriched uranium (HEU) or plutonium. HEU technology can be more easily disguised and concealed and is the route that Iran may be taking to build up its bomb-making capability. Plutonium bombs are easier to miniaturize for mounting warheads on missiles. North Korea’s first two tests
