That edge has dissipated if not totally disappeared but the delusion continues. There are just not enough assets to cover all of the mission requirements in a high intensity war.
Lose a squadron of F-22s or B-1s over time in a hot war, and you have effectively lost any qualitative advantage.
Not to mention how many times a squadron has been destroyed on the ground. Puerto Rican terrorists destroyed a squadron of A-7s on the ground. The Taliban destroyed several Harriers in a raid.
Low tech attacks on bases are a thing.
