This is tantamount to challenge to the line of the Workers' Party of Korea on simultaneously carrying on the economic construction and the building of nuclear forces, which is legalized as one of the DPRK's laws.

The U.S. has no face to call for denuclearization.

In actuality, the DPRK proposed the denuclearization of the Korean Peninsula against the U.S. nuclear threat to it and had paid big efforts to that effect.

In April 1959, the DPRK Government warned the U.S. of turning south Korea into a nuclear arsenal and offered a proposal for making Asia a nuclear-free zone.

In the hope of seeing the denuclearization of the Korean Peninsula, it joined the Non-proliferation Treaty in 1985. In the 1990s, it signed with south Korea a joint declaration on the denuclearization of the peninsula in a bid to defend the nation's security from the U.S. nuclear threat and made every possible effort for its implementation.

However, the U.S. has persistently threatened the DPRK with nukes, constantly creating a danger of nuclear war to the Korean Peninsula.

Soon after the DPRK conducted a nuclear test as self-defensive countermeasure, the U.S. launched Key Resolve and Foal Eagle joint military drills against the DPRK with mobilization of what it calls the three strategic nuclear strike means.

B-52 and B-2A bombers flew to the sky above south Korea to stage an exercise for dropping nuclear bombs while nuclear-powered submarines sailed to the waters off south Korea to attend the drills.

The prevailing situation goes to prove that the U.S. call for the denuclearization of the peninsula is no more than a trick to deceive the international community.

The facts have forced the DPRK to bolster up its nuclear deterrent, a guarantee for the nation's security.

The U.S. can never expect any dialogue for denuclearization with the DPRK unless it abandons its nukes.

Genuine dialogue is possible only at the phase where the DPRK has acquired nuclear deterrent enough to defuse the U.S. threat of nuclear war, unless the U.S. rolls back its hostile policy and nuclear threat and blackmail against the former.
