From a european perspective, I can tell you that the mood has shifted 180 degrees from "buy American fighters to solidify our ties with the US" to "can't rely on the US for anything which we'll need when the war comes".
Europe is wise and capable enough to develop their own platform.
I’m from one of those countries, and I can assure you a lot of people would now have preferred that we went with an EU competitor instead.
Countries are buying it because it is the only game in town for certain high-value capabilities, not because they necessarily like the implications of there being a single seller of those capabilities. For better or worse, the US has been flying these for 30 years and has 6th generation aircraft in production. Everyone else is still figuring out their first 5th generation offering.
Closing that gap is a tall order. Either way, European countries need these modern capabilities to have a capable deterrent.
You know the answer, but I'll say it anyway. There is no comparable alternative today, and there will not be one in the near future.
