I think that because the US has the potential to build a naval base in Morocco and the sz is always 1 turn away from 2 major complexes the proposal to turn off the naval base there indefinitely is impossible to sustain. Even if the base is bombed the US can still land in southern France and pass through to enter the med. if you conquer the territory you cannot hold it against determined American effort.
If the US is completely focused on the pacific than the bombing is still inconsequential. What bombing Gibraltar really does is divert planes from the critical path to Moscow. Their absence will cost additional units on the eastern front that are needed in that fight.
Not to mention that if a single aa gun hits you lose money because the base caps at 6 damage. Attacking the Gibraltar base is an interesting idea but is ultimately a vain effort.
I agree with that, its almost worthless. The only way to turn it off is to do a Sea lion and bomb Gibraltar and not take it and Morocco. The only problem is if the US decides its going to violate the Neutrality of the True Neutrals and Builds a Naval Base in Spain. Doesnt matter what you do, the US will find a way to make it work.
