And out of curiousity... what's to keep these other countries from swapping out the software and/or hardware that causes this? They bought it and the US can go pound sand. Am I saying it's easy to do? No. But it's not impossible and a far sight cheaper than buying all new planes from someone else.

Poland, Finland and all three Baltic states are buying F-35s, which is less than ideal.

I wonder what Putin would have to offer Trump to nerf, say, Estonia’s F-35s at an opportune moment.
