American air power would prove substantially inferior to the extremely potent and abundantly supplied air defenses arrayed against it in any of those three countries.

American suppression of enemy air defenses would prove woefully inadequate to the task.

And even if any of the US's aerial wunderwaffen were to prove, in ideal circumstances, to be potent weapons, US air power as a theater-wide undertaking could not be sustained in the context of a non-permissive regional and global battlefield.

In a high-intensity combat scenario in either eastern Europe, the China seas, or the Persian Gulf, the maintenance requirements for US aircraft could not be met. Mission-capable rates would plummet even lower than their notoriously abysmal peacetime standards.
