Isn't it kind of pointless though?

Russia has shown their "airforce" is vaporware that can be taken out by 60 year old tech.

China might have a legit airforce but their only real desire is Taiwan. It's not an actual threat to any western country in a military sense, because it doesn't' have to be. All it has to do is simply stop allowing the west to have access to it's minerals and they're all fucked unless they invade. Which is why China has an extremely strong defensive rocket and airforce.

The west is building an airforce to fight countries that don't have air forces to fight it instead of building ways to counter the things those countries actually have
