How do we know they dont have a boat or two..floating off the coast looking like a trawler that instead has a land Nuke 20 miles from Downtown L.A.? OR ..shudder,in SF bay?
How do we know the USA hasn't been told by NK,that they will detonate that bomb if we as much as find it?
More and more it looks like the Generals "We can defend against North Korea"is in reality not a defense,just a massive retaliation. One you hope happens as you die of NK fallout.
