What really puts all of this into perspective for me is I work in academia and one of my friends works for a defense contractor. He told me the maintenance cost per flight hour of F-35 was a bit more than $40k, which is significantly more than I make in a year as a grad student. It's crazy basic science is what's been the focus of so many cuts while it's so cheap.
How many million graduate students do you need to give the US the military hegemony and political influence over allies and adversaries that the F-35 program provides ? Looked at from a policy maker's viewpoint, things look very different.
Every single European country that already ordered them had immediately afterwards long hard talks about completely cancelling those orders and most ended up at least loweing massively the ordered amount (I presume due to contractual requirements and some money already sent, nobody expected backstabbing crooks on the other side when they were signed).
At this point its trojan horse and much worse than having nothing - it gives illusion of certain (extremely expensive) capability, but only if you lick specific ass hard and frequently enough, peppered with a billion here and there flowing in the right hands. Even then, the other side may be licking harder and thats it. Its ridiculous, and intensively insulting to every decent human being.
