@lin11c Thanks. "..the US could simply remotely turn off F-35s' advanced situational awareness capabilities", this is the ability I also mentioned to cut of the connections to radars, etc. which makes the F35 superior in combat. EU countries has those capabilities too, so they could replace it, but probably not in the quantities required, and it would take time to hack in. It's similar to Starlink in Ukraine; Eutelsat *can* replace it, but they don't have nearly the same coverage as Starlink.
