The Rafale and Eurofighter Typhoon, as well as Sweden's SAAB's jets, are all 4th generation jets. The F-35 is 5th. One project for a unified European sixth generation fighter jet was apparently cancelled in June of this year, as France and Germany couldn't agree on something or another. So the existing fighters will all turn obsolete soon, and the nations are incapable of agreeing what to do and will all have to work towards their own decisions for the future. Some turn to US's F-35 (or possibly the F-47 maybe in the future sometime, if the US can fix the 14 billion dollar hole in their MIC). Or maybe the Tempest, but that's not coming until 2035 apparently. The leaders here are expecting and preparing for a war with Russia by 2030 after all.
Despite the name, rare-earth minerals themselves aren't actually that rare. What's problematic is the lack of infrastructure around refinement of said materials into components that are actually usable in the defense industry. China controls most of the supply precisely due to their advanced refinement and manufacturing infrastructure, in addition to just mining. China currently controls approx. 90% of the entire supply of the rare-earths needed for military industry. Europe has no mines, and only two refineries, and apparently of those only one can process all 17 of rare-earths. 98% of the European need for these are imported from China. I have serious doubts as to the EU as it stands achieving any kind of independence from anyone.
Germany has been lauded as the workhorse of Europe for a while now, even though those in charge of the factories are currently shedding workers to save profits as capitalists tend to do. Volkswagen just announced its plans to shed 100k workers by 2030. These aren't the actions of healthy economies, or nations that are in any way ready for war. More like impotent threats from a bully who hasn't yet realized its larger friend's (US) legs are broken.
You didn't really answer any of my issues, just brought up more.
