 North Korea has argued that the U.S. has failed to fulfill its promises in the disarmament process, having not removed the country from its "State Sponsors of Terrorism" list or sent the promised aid to the country.The U.S. has recently stated that it will not remove the North from its list until it has affirmed that North Korea will push forward with its continued disarmament.North Korea has since barred IAEA inspectors from the Yongbyon site, and the South has claimed that the North is pushing for the manufacture of a nuclear warhead.
