Rodong Sinmun Friday says this in a bylined article.

It goes on:

The imperialists have long attempted to disarm and stifle the DPRK. After the Iraqi war, the U.S. openly revealed its intention to keep pressurizing the DPRK till it makes other option.

In recent years the U.S. has employed every possible means and method to bring down the social system in the DPRK as evidenced by the declaration of hostile policy to the DPRK, anti-DPRK psychological warfare and subversive and sabotage operations. This shows that the U.S. moves for invasion of the DPRK have reached the extreme phase.

The DPRK's permanent possession of nuclear weapons is attributable to the invariable aggressive nature of the imperialists and their policy for domination. It is the invariable ambition of the U.S. to militarily invade the DPRK and dominate the Korean Peninsula and the rest of the Asia-Pacific region.

It is clear that the U.S. will continue the moves to force the DPRK to give up the nuclear deterrence and bring down its socialist system and stifle it by tightening sanctions.

Strong is the will of the DPRK to strengthen the nuclear deterrence for self-defence to cope with the reckless nuclear threat and aggression moves of the imperialists and their followers. The DPRK will hold tighter the treasured sword, nuclear weapons.
