Recently Trump on twitter confessed that "the U.S. plan to set China in motion and check north Korea's nuclear development came to a failure" and the chairman of the U.S. Council of Foreign Relations said that "'denuclearization of north Korea' is an unrealistic goal".

This is a deploring sigh acknowledging their strategic misjudgment.

Since its emergence, the Trump administration fully disclosed the weakness of its DPRK policy.

The present U.S. administration has gone hell-bent to realize the "maximum pressure and engagement" after setting it as its DPRK policy, far from drawing a lesson from the failure suffered by the preceding administrations.

To look back on history, the U.S. suffered only big defeats in the stand-off with the DPRK. It was not attributable to the lack of intensity of pressure or scale.

It is by no means fortuitous that the international community is deriding the policies set forth by Trump as nothing different from the worn-out and obsolete strategies that had been pursued in the past.

It is the fixed faith and will of the DPRK not to make an inch of concession from the path of independence and justice.

In the course, the DPRK has towered as a world's power with military strength and self-fortitude based on the single-minded unity and nuclear force which no other country and nation have achieved.

On the contrary, the U.S. invited its ruin through madcap hegemonic moves, being obsessed by extreme arrogance and over-confidence.

Now is the 21st century, the era of independence, not the 20th century when the U.S. used to lord it over the world as the boss of imperialism.

The U.S. is running wild, unaware of the changed situation and who its rival is. Herein lie the tragedy of the U.S. and the strategic fiasco of the present administration.

The DPRK is foiling every move of the Trump group which is still going foolish, while resorting to the nuclear stick policy, and is strikingly manifesting the military might of nuclear power of Juche all over the world.

It is quite natural that the international community is commenting that "time has gone when it was considered that there would be no nuclear war in the U.S." and "the responsibility will rest with the U.S. in case a nuclear bomb is dropped on the U.S. mainland".

The Trump administration is still mired in the cesspool of anachronistic way of thinking, still retaining any lingering attachment to its ambition.

It is openly challenging the unanimous desire of the DPRK and the international community for peace and stability of the Korean peninsula with the "expanded south Korea-U.S. combined drill".

The U.S. foolish act will invite the catastrophic consequence of bringing the most horrible disaster to its mainland.

Strategic misjudgment is bound to lead to a final ruin.
