I think this article is making a story out of nothing.
George Washington will be taking apart in a joint US/ROK naval excercise that was due to happen anyway this summer but has been brought forward to next week after the sinking of the Cheonan to send a message of support blah blah blah...
Its a symbolic show of force that will last a few days and get media attention but does nothing to actually punish North Korea for the sinking of the Cheonan.
I could be wrong, but don’t those joint US/ROK naval exercises usually take place in the Sea of Japan?
The Yellow Sea is where all the post Korean War naval skirmishes have taken place between the ROK and NORKs
