NY TimesSEOUL, South Korea —
North Korea defied the United States, China and a series of United Nations resolutions by launching a rocket on Sunday that the country said was designed to propel a satellite into space, but that much of the world viewed as an effort to prove it is edging toward the capability to shoot a nuclear warhead on a longer-range missile.
The launching took place at 11:30 a.m. local time, said an official at the Foreign Ministry of South Korea who spoke on condition of anonymity until the government makes a formal announcement.The motivation for the test appeared as much political as technological: After acquiring the fuel for six or more nuclear weapons during the Bush administration, and negotiating a halt of its main nuclear reactor in return for aid, North Korea’s recent statements appear to be a bid for attention from the Obama administration.
Over the years the North has sometimes conducted tests as a gambit to extract concessions for more aid and fuel and to demonstrate its nuclear capabilities.
Manufacturing a nuclear warhead that is small enough, light enough and heat-resistant enough to be mounted atop a missile is far more complex than building a basic nuclear device — and intelligence officials and outside experts believe North Korea is still years from that accomplishment. Typically, it takes many years of experimentation for a nation to learn how to shrink an ungainly test device into a slim warhead.
Nonetheless, the series of tests in recent years — in 2006 and 1998 — is prompting fears of North Korean proliferation among Japanese, Chinese and Western leaders. North Korea’s missiles have ranked among its few profitable exports — Iran, Syria and Pakistan have all been among its major customers. If this long-range test ends up a success, it would presumably make the design far more attractive on the international black market.
