It is not as though NATO countries don't have a few Carriers of their own
Out of curiosity can you name a NATO country besides Britain that operates carriers? France doesn't count.
Spain and Italy have carriers I believe.
Italy has the 13,000-ton Garibaldi, which can carry 18 aircraft, and is building the 26,000-ton Cavour, which can carry 20+ aircraft and should be in service in 2008.

Spain and Italy. But they are very small "Harrier Carriers."
