I gander that there's a reason that we're the only country with more than one aircraft carrier.
And a smaller carrier would allow the Navy to field more of them at the same cost, which would mean being able to "show the flag" in more places simultaneously without having to run a few ships ragged trying to cover them all at once.
I'm not so sure when the more modest carrier is only seems capable of fielding VTOL aircraft:
> The America-class amphibious assault ships...are designed to put ashore a Marine Expeditionary Unit using helicopters and MV-22B Osprey V/STOL transport aircraft, supported by AV-8B Harrier II or F-35 Lightning II V/STOL aircraft and various attack helicopters.
