You understand that any nation that takes out a carrier has just started WWIII. At that point all bets are off. If you are advocating against carriers because they wont survive WWIII, then we might as well just not spend anything on defense.
Carriers, unlike missile silos, get more bang for tax dollar bucks, just because they are multi-purpose.
Duh. Anytime two first world nation go to war it is a world war.
