Rodong Sinmun Saturday observes in a commentary in this regard:

His invectives against the socialist system in the DPRK are no more than a manifestation of his uneasiness and frustration, prompted by the fact that any pressure does not work on the DPRK and it is winning victory after victory.

Before finding fault with others, Kerry had better think how the world people ridicule the U.S., tundra of human rights, which is perpetrating horrible genocide in different parts of the world in disregard of international law under the signboard of "freedom" and "democracy".

As far as the den of evils is concerned, the U.S. is the birthplace of evils.

The whole course covered by the U.S. is the continuity of wars for conquest leading to aggression, plunder, destruction and killing. The sovereignty of many countries was violated and their people shed blood due to the U.S. ceaseless state-sponsored terrorism, armed intervention and war of aggression.

It is none other than the U.S. which is bringing mankind the danger of a nuclear war and threatening the world by kicking up a new nuclear arms race, another Cold War, though it is talking about the "world without nuclear weapons" in the international arena.

The people of progressive countries aspiring after independence and peace are linking the U.S. with such disgusting names as empire of evils, the world's worst rouge state, harasser of peace and chieftain of war. The White House is a den of evils producing all evils in a serial way. This is the unanimous assessment of the international community.

The DPRK reminds Kerry of a saying: Dogs bark, caravan moves on.
