Well, this can’t be good:
More than 50 North Korean submarines have apparently been sent out on mystery missions, and artillery strength and warfare-readiness along the frontline have been raised to the max, a military source said Sunday.
That suggests the North has embraced a two-prong strategy tempering its traditional brinkmanship with diplomacy.
“The current sortie rate of North Korean submarines is as high as 10 times the rate in ordinary times,” a military official said. “Scores of subs that have left their bases on the eastern and western coasts are off our radar, which is an unprecedentedly serious situation.”
