Rodong Sinmun Monday observes in a bylined commentary in this regard:

Such an action is a smear campaign against the DPRK prompted by the U.S. persistent hostile policy toward it.

That the U.S. spoke ill of the inviolable independent rights of the DPRK before his stooges was an impudent and reckless action.

It was the U.S. hostile policy toward the DPRK that forced it to build self-defensive nuclear deterrence.

The DPRK could not but take steps to build such a deterrence to defend the sovereignty of the country and dignity of the nation and ensure the peace and stability on the Korean Peninsula and in the rest of Northeast Asia.

To urge the DPRK to give up everything and just sit bare-handed under such circumstances where there is no peace-keeping mechanism in the peninsula is just like expecting rain from the bright sky.

Explicitly speaking, it would be absolutely impossible for the U.S. to settle any issue with the DPRK unless the U.S. repeals its hostile policy.

The U.S. and its stooges in the joint briefing expressed tough stand, blustering that they would take decisive measures in the event of additional nuclear test or missile fire by the DPRK.

Clear to all is what this means. This precisely indicates their will not to rule out a nuclear war.

If the U.S. takes the "decisive step", the DPRK will answer it with tougher step.
