Pyongyang, June 23 (KCNA) -- The Headquarters of the People's Movement for the Withdrawal of the U.S. Forces in south Korea in a commentary on June 18 reportedly said that the abrogation of the south Korea-U.S. "mutual defence treaty" and the total withdrawal of the U.S. forces from south Korea are preconditions for the denuclearization of the Korean Peninsula. Noting that the U.S. has no right to say about the denuclearization of the peninsula as its forces are present in south Korea, ready to use nukes any time, the commentary said that the north's access to nuclear weapons is a just countermeasure to cope with the U.S. undisguised military nuclear threat. The denuclearization of the Korean peninsula can never come true unless the U.S. nuclear threat is completely gone, the commentary said, adding: If the U.S. truly wishes to see the denuclearization of the peninsula, it should pull out its forces from south Korea and normalize its relations with the DPRK.
