Rodong Sinmun Sunday observes in a bylined commentary in this regard:

The exercise is the manifestation of the U.S. sinister intention to hold military supremacy in the region by establishing triangular military alliance for aggression through sustained escalation of the situation on the Korean Peninsula.

It was originally planned to be staged as an open military drill involving the U.S. and the Japanese Maritime "Self-Defense Force", the commentary says, and goes on:

As the south Korean puppet army, whose participation was thought to be impossible, took part in the exercise, the U.S. announced that it would keep the exercise from being opened to the public.

This proves that it seeks a sinister aim in the drill.

While being bent on the frantic exercise, the U.S. called for "escalating pressure" on the DPRK.

This testifies to the fact that hostile forces' alleged drills for search and rescue operations for humanitarian purposes are no more than a military blackmail prompted by their foolish design to derail the DPRK's new strategic line on simultaneously advancing the economic construction and the building of nuclear force.

The disturbing movement of the U.S. for military supremacy in Asia-Pacific arouses due vigilance of regional countries.

The army and people of the DPRK consider the recent military drill as a poor rowdyism of those who were upset by the daily growing national capability of the DPRK.
