That depends on whether the pilots were willing to fire on Americans. Many, perhaps most, will not. And those who will are going to be at the mercy of those who will not on the ground. They will have fatal "accidents."
They’ll look at it as “servicing targets.” Doesn’t matter if they’re veterans. Look at what happened to the Bonus Army. Chased by their own brothers in arms, and killed in some cases.
They’re trained to follow orders. As I’ve said before, the term “illegal order” will be twisted beyond recognition. Those that have serviced targets before won’t see it any different, even if they’re from the same country, state, or town.
