The sophistication of the F-35 cannot be debated. But the rest of the world doesn’t trust the US anymore, so it doesn’t matter how good it is - people would gladly explore a worse product because they see it as lower risk.
That’s the reality of where America is at the moment. There are many Americans on Hacker News (if not the majority) and naturally the merits of the product that America produces are being discussed, and its superiority is front and center.
This viewpoint is not relevant to the rest of the world. We don’t want the US’ stuff anymore and the only thing that can save that relationship is full software control. If America wants to make sales it needs to adjust to that expectation, or buyers are going elsewhere.
The argument is missing the forest for the trees - the relationship is more important than the product itself. The sooner that is acknowledged the more likely a political course correction is possible. Otherwise, sure, you might see a few short term F-35 sales conclude. But the purchasing will stop as soon as it can.
