The U.S. ambassador in Seoul jabbered that Washington takes a serious note of north Korea's military muscle.

Rodong Sinmun Saturday observes in an article in this regard:

The U.S. had better recollect its frequent nuclear blackmail with nuclear strike means by staging war rehearsals aimed to "liquidate the headquarters" of the DPRK and "occupy Pyongyang" before talking about "threat from north Korea."

The U.S. bellicose forces are making shrieks, complaining that they can hardly have a sound sleep. This is a natural product of their hostile policy toward the DPRK, the article says, and goes on:

The service personnel of the DPRK are bolstering up at a remarkably high tempo nuclear deterrence for self-defence with its powerful strategic strike means as a mainstay now that the U.S. hostile policy toward it gets ever more undisguised.

It is long since the DPRK entered into the full-fledged stage of manufacturing smaller and diverse nuclear strike means. It does not hide the fact that it has reached the phase of ensuring the precision and intellectual level and the highest rate of hits of its long-range rockets.

Aggressors can never find any safe haven.
