Yes of course it's France's fault.
Weird how France could do the Concorde with the Brits or CFM International with the Yankees; but when it comes to working with the Germans, things crash and burn. Like the Eurofighter Typhoon. Ask the Brits if they want to make the Tempest with Germany... But no, it's France's fault.
Story of FCAS in a nutshell:
Germany says "hey France, how about making next-gen jets and tanks together? I'll take the lead on the tank and you take the lead on the fighter, okay?"
Then Germany says "actually, the fighter thing is a big deal. Let's split it into several parts. You keep the lead on the fighter proper, of course, but I'll take the lead on the engine, on the drone wingmen, and on the networking. Also on the tank thing, we're gonna bring in more German companies than originally agreed so we'll reduce your part here, but that's fine, right?"
Then Germany says "actually, we want the lead on some parts of the fighter too, like flight commands. Also, we're gonna buy the F-35 anyway. The idea is that you buy the jet we produce, and we buy the American jet instead."
Then France gets pissed off and it's France's fault. France just doesn't play well with others...
