The internal conflict is that the European planes that exist are nowhere as capable as the F-35.
While the European defense contractors may promise a comparable plane, they have a poor track record of delivering such a thing anywhere close to the near future.
Well unless we in Europe want to do in direct conflict with US (ie for Greenland), this is mostly irrelevant extra capability. As Ukraine shows, peer conflicts are won by other means, not stealth air superiority over sheep herders with AKs.
Some general's wet dream of dogfights in Maverick's style are modern day fantasies. What those planes are used for are just lobbing glide bombs or shooting missiles. Their biggest enemy is on ground. Sure, small radar signature helps massively but that's not enough. Otherwise US would send 500 F-35 into North korean airspace and wipe out most of its military... not going to happen.

I don't think you can conclude that when neither of the belligerents has the capability. As Gulf War shows, training and capabilities (including stealth) do enable SEAD/DEAD to an extent that unlocks air superiority.
I don't understand what that link is supposed to prove. A single F-117A getting shot down in Yugoslavia due to complacency and chance doesn't negate Nighthawks bombing SAM defended areas with impunity. Iraq had a strong and integrated AD network for the time.
Air superiority alone doesn't, but it's a massive force multiplier.
I read it and I know about that case. However, as I said I'm struggling to see your point.
I guessed you meant that that one case proves something about air superiority or Iran having an advantage over USAF, so I responded with a historical parallel.
I talk about peer conflict, which Gulf war wasn't. Old soviet tech, poorly trained soldiers with very low morale doesn't make them anyhow a peer to US army of that era. It was just a variant of that shooting goat herders, defenseless even against Apache choppers who have 0 stealth and fly low & slow.
