This proves that the U.S. imperialists have steadily renewed and developed their scenario for a nuclear attack on the DPRK.

Rodong Sinmun Monday says this in a signed commentary.

Citing facts to prove that the U.S. imperialists have so far worked hard to realize their variety of scenarios for igniting a new war in Korea, it says:

The historical facts and the present reality testify to the fact that the DPRK was entirely right when it came to the conclusion that it was the only way to cope with nukes in kind.

It was the exercise of the DPRK's legitimate right to self-defence that it had access to nuclear deterrent to cope with the U.S. increasing nuclear threat.

The DPRK's access to nuclear deterrence was required by the prevailing situation in which the danger of a nuclear war to be provoked by the U.S. on the Korean Peninsula is becoming real and a step taken by it to firmly defend its sovereignty and Korean-style socialist system.

No one can guess when the DPRK will come under the nuclear attack of the U.S. imperialists as these trigger-happy forces are further stepping up their moves to stifle the DPRK than ever before over the "Cheonan" case. That is why the DPRK has paid a special attention to bolstering up its nuclear deterrent.

The serious situation prevailing on the peninsula requires the DPRK to bolster up its nuclear deterrent in a new developed manner.
