Rodong Sinmun Wednesday says this in a commentary.

If the U.S. is truly concerned for the improved DPRK-U.S. relations, it should make a bold decision to withdraw its aggressor forces from south Korea without delay, it notes, and goes on:

The U.S. warmongers opened to public even a strategy for preemptive nuclear attack after staging ceaseless maneuvers for a nuclear war by introducing nuclear carriers in the wake of the involvement of strategic nuclear capable bombers. It is needless to say the proposal for concluding a non-aggression treaty touted by them is nothing but a poor farce.

The aim sought by the U.S. in deliberately escalating the tension quite contrary to the patient efforts of the DPRK, a nuclear weapons state, for peace is to bar it from achieving economic prosperity and justify its arms buildup aimed to maintain a military edge in the Asia-Pacific region.

This is the reason why the U.S. is persisting in military provocations, desperately defying the DPRK's just call for ensuring peace and stability on the Korean Peninsula through dialogue and negotiations without any precondition.

It is the height of shameless and crafty nature of the U.S. to urge the DPRK to drop its arms first and propose it to conclude the non-aggression treaty.

The Korean people have keenly realized through life experience that the U.S. proposal for concluding the above-said treaty cannot protect peace and security on the peninsula but the DPRK's self-defensive revolutionary armed forces possessed of nukes can protect and guarantee everything.

If the U.S. truly wants to improve its relations with the DPRK, it should properly understand the latter and take a right stance.
