Please excuse me for being a little dumb here, but the main point of having an armed force is to protect Great Britain's assets at home and abroad?
For some odd reason I wouldn't trust the great US of A to go out of their way to help us if we did have another Falklands. For that reason alone personally I believe that we should have a fully formed navy, not one missing crittical assets like a carrier. How many times do we have to learn the lessons?
