If selling the carriers maybe they will do a "buy 2 get 1 free" deal ;-)
Serriously wasn't there talk off India buying a due out off service carrier from the US navy cheap (ie a dollar) as long as they bought F/a-18's????
If America wants to be the world police they need the equipment to do it, don't think they could operate the way the UK forces have had to operate ie so thinly based .
So in my opinion it's more about how they wish to be seen and how they want there infulence to be enforced !
