After the end of WWII the U.S. designated the DPRK as the main target it has to stifle in the Asia-Pacific region, the article, said, and went on:

The U.S. hostile policy towards the DPRK has deep roots.

It enforced the hostile policy towards the DPRK long before the nuclear issue spawned on the Korean peninsula. They neither established diplomatic relations with the DPRK nor called the official name of the country properly.

After the Korean War the U.S. reduced south Korea to its military base for aggression and has resorted to all possible means to stand in the way of the improvement of the inter-Korean relations. The U.S. is making desperate efforts to realize their domination over the whole Korean peninsula.

It also framed numerous scenarios to stifle the DPRK which are in the course of implementation.

The historical truth clearly proves that the hostile policy towards the DPRK was not caused by the possession of nuclear weapons by the DPRK but Pyongyang was forced to have access to the nuclear weapons due to the Washington's hostile policy.
