Carrier-based air is always more "convenient" and more readily available on a short time notice, and without having to "negotiage" with "allianaces" for the "right" to use their land, their concrete, and hteir airbases.....nver-mind whether we built them in the first palce or not.
NO land-based air base in ANY country (Vietnam, Germany, Japan, Formosa, Philllipines, Malaysia, Thailand, Argentia, Falklands, Israel, Egypt, Libya, Lebanon, Syria, Iraq, Iran, etc.) has NOT, in the past many years, worked worked very well when assaulted by missiles, bombs, fighter-bombers, or simple mortors.
So take your pick: Cheap (and easily shut-down (if operable at all - the French denied us permission to cross over or land in France when bombing Libya)) or expensive and available.
