It would be ending a relationship with any country that uses F-35s. Sorry, but you’re a child if you think there’s even a snowball’s chance in hell of a company risking their exclusive manufacturing of a component that could easily be produced elsewhere if there was a demand. You think the message from the company would be “We will not support Israel’s actions!” but the only message buyers will hear is “We’re an unreliable company that should not be trusted as a supplier!”

This post is like saying only one company makes the paint used to mark the bombs, so we can stop all the bombs by not making the paint; completely ignoring that the paint isn’t all that critical, there is already plenty of spare supply out there, and practically any other company could start producing more if it was really needed.
