Referring to the successful test of H-bomb, nuclear warhead explosion test, test-fire of surface to surface medium- and long-range strategic rocket Hwasong-10, test-fire of SLBM, etc., the author went on:

It is necessary to disclose the real intention of sophism made by the U.S. and the West in order to be aware of whether the nuclear weapons of the DPRK constitute "threat" or not.

1. "Nuclear tests of the DPRK damage ecological environment of surrounding countries."

The survey results by experts in the Far East region of Russia and neighboring counties of China show the contrary results.

The nuclear tests of the DPRK did not have any bad impact on ecological environment of surrounding areas.

2. "DPRK is going to attack U.S., Japan and south Korea."

This is based on the "assertion" of the U.S. and its followers who are repeating stereo-typed rhetoric.

It is none other than the "democracy"-advocating U.S. which used first the nuclear weapon against other country.

The reality in the DPRK is contrary to that touted by the U.S. and the West.

3. "Nuclear tests of the DPRK will seriously damage its neighboring countries as their blast intensity is tremendous."

This was out of ignorance of the reality of the DPRK.

The DPRK is making economic development and it stays ahead of the world in the latest technology.

It has excellent nuclear experts with rich knowledge and technology.

That is why the probability of destructive crisis is zero.

The author stressed that now the U.S. hostile policy toward the DPRK made its nuclear position stronger and the nukes of the DPRK are not dangerous as compared with those of the nuclear powers.
