OK squidly didly, I'll deal with it. You said that since all these other NATO countries operated "carriers" that training them up in operating a CV would be no big deal.
None of the carriers you refer to have arresting gear. None have catapults. None have steam turbines--all have gas turbines. None use the same radar and electronics suite as the JFK.
So, Maverick, you are wrong. Go pick some rust.
