The thing is, we waste so much money it's better to crash 15 jets but build 2000 of them than waste the same amount of money and build 5 jets.
Even us SWEs out in the wild, we sometimes... disable tests (gasp heard everywhere) so that a refactor can work.
I mean it's why we have the expression "sometimes you have to crack a few eggs".
It's why WWII vets did what they did knowing not every bomb, aircraft or handheld weapon was perfect but still ran in to stop Hitler. I would say that put a high price on human life. These last few generations won't get it until it gets its WW.
There is a reason why USA is currently seen as the biggest threat to stability - because USA is intentionally trying to make the world unstable.
There is literally no one that can bomb the US into nothingness. Even if the US decided to stop develop new weapons, they cannot be invaded. They are too big, too rich and too protected by the ocean and weak neighbors for that
