I'm not particuliarly worried if we have to pull our men out. We got plenty of firepower aimed at a potential enemy.
I don't want to see it, but men have become tinfoil now. They are border guards. Sometimes I just have to shake my head how much our battle groups can bring to bear even in a conventional mode.
The biggest real danger is that someone will have the balls to use a low observable missle against a supercarrier. Especially nuclear.
