Rodong Sinmun Friday observes in an article in this regard:

Every politician responsible for the destiny of the U.S. should properly understand who its rival is, though belatedly, and had better stop going reckless.

Since the emergence of the Obama Administration, it has pursued a "strategic patience policy" that the U.S. waits for the DPRK to yield to it after ceasing all its nuclear activities and dismantling its nukes, and resorted to sanctions and pressure upon the DPRK in denial of any dialogue with it.

The DPRK's decision to have access to nuclear deterrence was an option it was compelled to take in face of the U.S. hostile policy, ceaseless military pressure and nuclear threat that have lasted for more than half a century since its foundation.

Taking issue with the DPRK's launch of satellites for peaceful purposes and politicizing and internationalizing it, the U.S. slapped collective sanctions against the DPRK by mobilizing its allies.

Kicking off hysteria over every trifling move of the DPRK, the U.S. wooed the UN Security Council into issuing what it called "statements".

As the U.S. clarified its stand to bring down the social system in the DPRK at any cost, brandishing its nuclear club, the DPRK had no choice but to react to the U.S. nukes in kind.

The nukes of the DPRK are deterrence for self-defense to be maintained and bolstered up till the U.S. nuclear threat and blackmail are terminated. They are, at the same time, just treasured sword to break the cursed nuclear club of the U.S. and establish an international fair order.

The U.S. was chiefly to blame for compelling the DPRK to have access to nukes though it was keen to focus its efforts on economic construction and the improvement of the people's standard of living. With nothing can the U.S. block the advance of the DPRK.
