Not content with this, the U.S. is mulling increasing its speed to be six times faster than the sound speed. If this is put into practice, the U.S. would acquire the capability of striking any region in the world in a few minutes.

Minju Joson Wednesday observes in a bylined commentary in this regard:

All facts point to the U.S. persistent dream of world domination based on military edge by putting the whole world in the striking range.

This is why the U.S. is working hard to develop latest weapons such as ultra supersonic drone.

The real aim sought by the U.S. is to quell by force of arms any country standing against its strategy for dominating the world.

This was proved by its stepped-up development of Bunker Buster.

Bunker Buster is a new-type special bomb which the U.S. is developing allegedly to destroy Iran's underground nuclear facilities.

This behavior of the U.S. is a main source of worldwide arms race.

Threat to global peace and security comes from the U.S. It is impossible to achieve permanent peace and security of the world unless the U.S. gives up its scenario for world domination based on its military edge.

The U.S. had better stop such an impudent act of mocking at the world through deceptive rhetoric about "peace."
