The participants asserted that what remains unchanged up to this date is the "U.S. ignorance of north Korea" and its groundless "theory of its collapse" and what has altered is the "bolstered nuclear capability of north Korea" and "smaller opportunity of U.S. option".

There were criticism and louder voices that "north Korea's abandonment of nuclear program is impossible" and "there is no way but dialogue."

This indicates that the U.S. hostile policy toward the DPRK is censured even in the U.S. mainland as a failed policy.

The structure of confrontation between the DPRK and the U.S. is turning unfavorable to the U.S. due to its policy for stifling the former.

The U.S. dream of occupying Korea through nuclear blackmail and political and economic pressure and, furthermore, using Korea as a bridgehead for carrying out its scenario for dominating the Asia-Pacific went up in smoke due to the DPRK's access to nuclear weapons.

The U.S. arms buildup stepped up under the pretext of coping with the DPRK's nuclear force is making the U.S. financial condition more difficult.

The U.S. is crying in distress that the fate of its cities is put at peril due to the increasing number of nuclear weapons and missiles in the DPRK. It is also seized with fear that the unchallenged edge of its nuclear force may sink. Such uneasiness and fear were caused by itself.

20 years ago when it signed the DPRK-U.S. agreed framework for the settlement of the nuclear issue, the U.S. calculated that if it deterred the DPRK from developing atomic energy industry and employed delaying tactics, the DPRK would "collapse" soon.

Such wild dream remains unchanged even under the Obama administration as was the case with the Bush administration.

The U.S. policy-makers dreaming of only the DPRK's disarming and "collapse" will only face such consequences as uneasiness and fear caused by the DPRK's access to nukes and their qualitative and quantitative increase.

The U.S. hostile policy toward the DPRK is like a foolish suicidal policy as it throws the whole of the U.S. into an abyss of ruin.

The voice of despair heard from among U.S. experts amounts to the recognition of this stark reality and an expression of rebuff to the responsible politicians.

The U.S. would be well advised to roll back its hostile policy toward the DPRK if it considers the DPRK's move to bolster up its nuclear capability as a threat to the U.S. strategic security.
