No sooner had the DPRK succeeded in the nuclear warhead explosion test than the U.S. president reeled off invectives, the statement said, and went on:

The test was part of the DPRK's practical countermeasures to cope with the nuclear war threat and sanctions by the U.S. and other hostile forces.

Lurking behind the "statement" announced by Obama before the expiration of his tenure is his real intention to evade the blame for pushing the DPRK to have access to nuclear weapons.

Obama is working hard to deny the strategic position of the DPRK as a full-fledged nuclear weapons state, a foolish act to eclipse the sun with his palm.

The DPRK is firmly taking hold on the line of simultaneously pushing forward the two fronts in order to protect its sovereignty, vital rights and peace from the ever-increasing U.S. nuclear threat and blackmail.

The recent test is only one process of implementing the above-said line.

The U.S. policy toward the DPRK goes totally bankrupt.

It should acknowledge the DPRK as a nuclear weapons state.
