The article recalled that days ago the DPRK succeeded in the nuclear warhead explosion test, adding:

The world was greatly shocked by this hard reality.

Media said that sanctions and blockade don't work on the DPRK, the said test proved it and the DPRK is substantially capable of targeting the U.S. mainland but the latter has no way to repel it, adding the U.S. strategy faced total failure.

The U.S. must draw a lesson from the DPRK-U.S. standoff.

No military power, sanctions and blockade ever work on the DPRK. If the U.S. neglects it and stubbornly pursues the hostile policy towards the DPRK, it will only face worse calamities.

The U.S. is well advised to look back upon the lessons of history and make a bold switchover in its policy.
