The DPRK's successful test-fire of strategic ballistic rocket Hwasong-10 sends a strong message to the world, the commentary notes, and goes on:

The strategic structure of standoff between the DPRK and the U.S. and the trend of the situation have dramatically changed.

In the last period, there existed only the unilateral nuclear threat and blackmail of the U.S. in the DPRK-U.S. relations. Consequently, extreme tension prevailed on the Korean peninsula.

But, the U.S. mainland is now exposed to threat.

The U.S. imperialists leveled the areas of the DPRK to the ground in the period of the Korean war, claiming that the latter would not be able to stand on its feet even in a hundred years. More than six decades since then the U.S. mainland may be reduced to debris.

Just as the U.S. has put staging madcap nuclear war drills by introducing nuclear strategic assets into south Korea on a "routine basis," the DPRK's efforts to bolster up its nuclear deterrence have become routine.

The DPRK's capability to make a preemptive nuclear attack will be further bolstered up in the future.

It is the U.S. and its followers who will suffer from extreme terror and horrible nightmare with the passage of time.

The U.S. and the south Korean puppet group are trumpeting about "denuclearization" from an anachronistic viewpoint. But it is too late. It is hard to turn back the clock of history.
