The present U.S. ruling quarters would be well advised to recollect what a bitter cup of setback the former Bush administration drank while taking a wrong approach towards the DPRK with a twisted way of thinking.

The Bush administration openly revealed its intention to antagonize the DPRK and isolate and stifle it, the article says and goes on:

The DPRK had legal and legitimate access to nuclear weapons to protect the sovereignty of the country and the national security from the U.S. nuclear threat getting evermore undisguised.

The U.S. should have drawn a due lesson from the baneful consequences of its hostile policy towards the DPRK, though belatedly.

However, the U.S. made the same mistake, failing to draw a proper lesson from its failed hostile policy towards the DPRK after its chief executive was replaced by the other.

The Obama administration has made desperate efforts to stifle the DPRK by floating the "rumor of collapse" of its social system, something that will never happen.

The U.S. knew nothing about the spirit and mettle of the army and people who were dashing ahead like the wind towards a thriving nation by dint of single-minded unity.

There are only two options for the U.S.

The first is to make a bold switchover in the Cold War mentality and roll back its anachronistic hostile policy towards the DPRK to contribute to the peace and security on the Korean peninsula and ensure the security of the U.S., too.

The second is to persist in its hostile policy as now. In this case it will compel the DPRK to reinforce its nuclear arsenal.
