As for the gentleman suggesting America should not have tried to make the world a better place; here’s a different take:
I think you’re conflating 2 things; making the world a better place based on realties of that place or making the world a better place based on a distorted vision/special interests which in layman terms amount to foreign meddling. I am 100% with option 1 so long as it not transformed magically to option 2 and you philosophies/overcomplicate it the way want.
In other words don’t make a mess by intervention where you don’t understand the dynamics or history of the place/imposing solutions that don’t fit then come to say we failed cause we tried to make the world a better place. Makes sense??
