I mean, the F-35 is a 5th generation fighter, and though it's US made, it is available to all Nato Allies, and several countries that aren't even in Nato.

It doesn't quite hold up to the F-22, but it is still a capable 5th gen fighter.

And the the Su-57 is questionable as to whether or not it counts as 5th generation. It's built according to 4th generation strategy, but it's definitely a far more advanced fighter than any 4th generation fighter. It does have some stealth and 5th generation design concepts, it just prioritizes dog fighting and maneuverability. There is still some debate on whether at a certain degree of large scale aerial combat it could become a superior fighter, but this is appearing less and less likely.

Also 6th generation fighters are already far closer than most people realize. Japan should have their first prototype F-3 in 2024, and China and US are both on similar timelines.
