DPRK is doing again what has worked for them in the past: tell the world they are blameless and the evil puppet ROK government is acting as its master, the United States, pulls its strings. This is good for internal consumption but doesn't play well in the real world.

The USS George Washington is sailing into the disputed area. This is a BIG aircraft carrier with its accompanying flotilla.

The US currently has no nukes in Korea -- they were removed in, I believe, 1991. It was a funny sitiuation: for example, we has 138 nuclear warheads for the Davy Crockett weapon but no launchers. I suppose we were supposed to throw them.
