Rodong Sinmun Tuesdays says this in a bylined article. It goes on:

The DPRK's access to nuclear deterrent is the exercise of its just right to defend the supreme interests and peace of the country from the vicious moves of the U.S. and the south Korean puppet forces to invade the DPRK.

The U.S. has recently amassed its military forces in the Asia-Pacific region as part of its aggression moves against the DPRK.

The DPRK's smaller and powerful precision nuclear deterrent is making futile the U.S. and the puppet forces' attempt to ignite a nuclear war against it.

With the U.S. becoming evermore undisguised in its frantic attempt to ignite a nuclear war, if the DPRK had not have a powerful nuclear force, a thermonuclear war would have broken out on the Korean Peninsula.

The DPRK will never abandon its nuclear force as long as the U.S. persists in its aggression moves and threat of nuclear war against the DPRK.

The U.S. and the puppet forces should never dream of making a deal with the DPRK over its building of nuclear force at the DPRK-U.S. or north-south negotiations.

Steadfast is the DPRK's stand to glorify it as the best country that any aggressors dare not invade, and achieve the historic desire for national reunification with economic construction and the building of nuclear force as a pair of pillars.
