After the test, the North's nuclear weapons institute said it will take unspecified measures to further boost its nuclear capability, which analysts said hinted at a possible sixth nuclear test. Moon refused to say what specific evidence pointed to another possible North Korea test. North Korea's pursuit of missiles and nuclear weapons is one of the most intractable foreign policy problems for the U.S. and South Korea. Six-nation negotiations on dismantling North Korea's nuclear program in exchange for aid were last held in late 2008 and fell apart in early 2009. The Korean Peninsula remains technically at war, as the 1950-53 Korean War ended in an armistice, not a peace treaty.
