In a conventional war, "this weapons system works perfectly after we completely dismantle their air defenses" sounds pretty similar to "this works perfectly after we win", IMO. And, theoretically, the F-35 can be used for operations before that happens, which is part of why they're being put into service.

Not to mention "this plane works fine if we get the Navy to do the hard part first" is going to go over well with a rather limited subset of Air Force personel. (The Air Force has wild weasels too - generally F-16s though I believe the F-35 is planned for that role in the future)
