The 11 carriers are needed to ensure that there is at least some power projection. Just because most carriers are in the hands of allies does not mean that we do not need them - carriers aren't for attacking other carriers, but projecting air power over potential warzones.
For example, lets say a theoretical war starts in SE Asia, and Australia gets attacked. Australia wants our help. How are we going to provide air power to Australia if it is behind enemy lines? That is what aircraft carriers are for - mobile floating fortresses that can project strikes onto enemies.
And its precisely for that reason I want our troops out - the whole idea on having so many people overseas in bases is for power projection. Why do we need power projection like that when we have 11 said carriers?
Essentially, I want to see America like this (militarily):
Reduce our presence in Europe by 90% or more
Reduce our presence in Asia by 50% - force Korea, Taiwan and Japan to care about their own military for once
Remove all troops from Latin America and Africa
Reduce our presence in the Mid East by 80% (sans Diego Garcia)
To compensate for that, field about half of our carrier fleet around the world in case of wars, with the other half at port, ready to move in the case of a war.
Back from the dead, I'm afraid.
