Involved in the drills are huge aggression forces, including the U.S. and south Korean puppet troops and forces of various vassal countries, and all types of strategic assets such as U.S. nuclear carrier, nuclear submarine and nuclear strategic bombers.

The U.S. secretly introduced ammunition and equipment of more than six million tons into south Korea from the end of last year. It recently took a measure for urgent evacuation of the families of the U.S. imperialist aggressor troops present in south Korea and American citizens staying there ahead of the joint military drills.

From a historical point of view, the nuclear war drills of the U.S. and south Korean puppet troops have been the root cause of the touch-and-go situation on the Korean peninsula and they compelled the DPRK to take the strongest counteractions.

Even at this moment, the "4D Operation" aiming at a preemptive nuclear attack on the DPRK is being put into concrete shape through nuclear war drills and exercises targeted neighboring countries are openly staged under the simulated conditions of THAAD deployment.

Nevertheless, the U.S. asserts that its every nuclear war drill in south Korea is "annual and defensive" to cope with the DPRK's access to nuclear weapons. This is nothing but a cynical ploy to shift the responsibility for the escalating tension on the peninsula onto the DPRK and justify its scenario for aggression.

It is legitimate right of a sovereign country to self-defence to maintain high alertness for action as required by the grave situation in which a war may break out any moment and bolster up in every way the war deterrence capable of mercilessly wiping out the aggressors.

Peace has been preserved on the peninsula despite the outrageous moves of the U.S. imperialists for a nuclear war entirely thanks to the DPRK's resolute will and efforts to protect peace and its tremendous nuclear deterrence for self-defence.

With no rhetoric can the U.S. cover up its true colors as an arch criminal escalating the tension of the peninsula.
