Stapleton Roy, former U.S. assistant secretary of State and other former high-ranking officials, experts on Korean affairs and major policy research institutes of the U.S. are strongly insisting that the U.S. administration should opt for improving relations with the DPRK for the sake of the security in the mainland, the article says, and goes on:

These assertions might be made after serious study and discussion.

The unilateral nuclear threat and blackmail against the DPRK have proved futile and sanctions are unworkable. Military pressure and sanctions only result in pushing the DPRK to bolstering up its nuclear force on a high level.

The DPRK ranked itself among nuclear weapons states entirely because of the U.S. hostile policy toward the former.

The denuclearization of the Korean peninsula is inseparable from the denuclearization of the U.S. and the world.

The DPRK's strategic position as a nuclear power remains unchanged no matter how hard the hostile forces may try to deny it.

The desperate efforts of the U.S. to save its hostile policy toward the DPRK from its total bankruptcy would only prompt the latter to redouble its efforts to bolster up its nuclear force on a high level.

It is a pipedream for the U.S. to try to stifle the DPRK with the harshest sanctions.

The U.S. option for rolling back its hostile policy toward the DPRK is for the good of the U.S. itself. The U.S. persistent pursuance of its hostile policy toward the DPRK would put the security of its mainland at greater peril.
