In the 1990s, despite issues surrounding the controversial US-South Korean joint Team Spirit military exercises, the Clinton administration still managed to help turn around the situation regarding peace with North Korea through Jimmy Carter's support. It promised light water reactors in exchange for the availability of North Korea for inspection of its facilities and other concessions. North Korea reacted positively, despite blaming the United States as the original aggressor in the Korean War. There were attempts to normalize relations with Japan as well as the United States with South Korean President Kim Dae-jung in open support. North Korea actually favored the United States military's position on the front lines because it helped prevent an outbreak of war. Eventually, aid and oil were supplied, and even cooperation with South Korean business firms. However, one of the remaining fears was North Korea, with their necessary uranium deposits, having the potential to achieve a high level of nuclear technology.
