Four Aegis ships including John S. McCain of the U.S. imperialist aggression forces and nearly 30 warships of the south Korean navy including destroyers, patrol craft, logistic support craft and submarines have been busy kicking up war hysteria in waters off the Korean Peninsula since March 13.

Cheyenne, a nuclear submarine belonging to the U.S. 7th Fleet equipped with vertical launch cruise missiles and sophisticated system is also involved in the drills.

It arrived at Pusan Port on Wednesday while the maneuvers were under way.

The combined naval drills including marine interception, firing, missile monitoring and anti-submarine exercises will reportedly go on till March 23.

The on-going saber-rattling is obviously a nuclear war exercise aimed at a preemptive attack on the DPRK.
