They said that the carrier task force of the U.S., with nuclear carrier Ronald Reagan as a prototype, was conducting large-scale naval exercises combined with a drill for striking key facilities in the north and anti-submarine exercises.

This is a military threat with the intensive deployment of forces enough to mount preemptive strike any time, they said.

The north already warned of military action including a salvo of missiles into waters near the U.S. territory of Guam and therefore it is clear that if the U.S. nuclear carrier commits an advance into the north, there will occur serious military conflict.

The regime claims opposition to war but, in fact, it is calling for sanctions and pressure, straining the tension in close cooperation with the U.S. military action, they charged.
