It's mixed. But even if you stick to older generation chips, someone has to supply them which means someone has to make them. Foreign manufacturing and sourcing is a political and security headache even if you go through the hoops to show a secure supply chain and address all their concerns. I had "cybersecurity" people refuse open source project use because someone in France (an ally) had a commit. Don't let them look at the Linux kernel commits... I wouldn't want to deal with that for hardware. Also F-35 is not something anyone should aspire to. That system, its software in particular, was a project management disaster. LM went to shifts to try to address being late to complete the software. They literally thought they could double or triple their staff to catch up, idiots had never read The Mythical Man Month apparently.
