The Korean Central News Agency (KCNA), the offcial news agency of the Democratic People's Republic of Korea (DPRK), issued a commentary on Tuesday to accuse the U.S. of posing nuclear threats to the world.

According to the commentary, the United States has continued secret nuclear weapons testing that has brought to light the hypocritical and deceptive nature of America's commitment to prohibiting the development of nuclear weapons and tests.

The U.S. has conducted nuclear tests more often and has greatly increased the fund for nuclear-related activities. It keeps deploying nuclear weapons in different regions of the world and escalating the danger of a nuclear war on the Korean Peninsula. The reality goes to prove that the U.S. nuclear policy for aggression can never change, said the commentary.

"It is the invariable strategy of the U.S. to dominate the world by monopolizing nuclear weapons and holding hegemony in the field of strategic offensive weapons", said the commentary, stressing "it still remains the arch criminal which has posed nuclear war threats to the world and sparked an arms race."

The U.S. talk about "denuclearization" is aimed at preventing all other countries and regions from having access to nuclear weapons, said the commentary.

At the end, the commentary urged the U.S. to "stop making a mockery of the international community and give up its nuclear ambition."

According to the KCNA, the Kyodo News reported on Jan. 6 that the U.S. conducted a plutonium test based on new technology in order to examine the power of stockpiled nuclear weapons last summer.
