Rodong Sinmun in a bylined article says this on Friday.

It continues:

This reflects the will of the Korean People's Army and the people of the country to fight a decisive battle to put a final end to the long-standing history of confrontation with the U.S., and to win a final victory in the great war for national reunification.

As the state of war was declared, all agreements which had so far guaranteed the armistice and non-aggression on the Korean Peninsula have been completely scrapped in practice.

In case there is a slight sign of provocation, the offensive weapons mounted with nuclear warheads as well as long-range artillery pieces will immediately deal physical counter-strikes at the provocative bases without any notice.

It is by no means threat and demonstration of armed forces.

The DPRK will mount preemptive nuclear strikes, merciless and thoroughgoing, to any place whether it is the Military Demarcation Line, the five islands in the West Sea of Korea and the U.S. mainland, once the sign of provocation is observed, so that the provocateurs can no longer pursue any daydream.

The strike of the DPRK will not be confined to a local war, but will be a signal flare marking the start of a holy war for national reunification.

If a war is unleashed on this land against the will of the Koreans as a result of the consequences entailed by the U.S. and its south Korean puppets' unpardonable actions, the provocateurs can not escape their ultimate doom in the war.
