I would expect that, for now, at least the Med. is out. I say this based on "the international security climate".
A Dis ship that close to the Middle East would make too tempting a target as an American Icon.
Given the demographics (i.e. two ships on east coast, none on west coast), that points to a west coast ship.
With the popularity of Alaska, I'd bet my money there, 2:1.
