All of them attacked simultaneously? Apart from Russia and China, which country has the means to attack those bases? Name it. Russia and China have no interest any more in attacking the US or its bases anywhere (come to think of it, they never did) but should they so desire, it'd be much easer, with the weapons they have, to target a big fat 100,000 ton carrier than bases. Bases may be damaged badly, but can be repaired or moved. Not so a sitting duck carrier.
A sitting duck is like the USS Cole that was in an unprotected harbor while refueling!<quoted text>N. Korea, India, Pakistan, Iran, Egypt, Libya, and Syria.
It would be kind of hard to use a base if a missile destroys a nuclear powered ship or a ship that has nuclear weapons on it, in the harbor.
