Many of the places you're talking about were completely fucked by colonialism. Africa and many third world countries are still having their wealth extracted by nations with more power and influence.

I think that we'd find Americans in the same circumstances as them would likely not act much differently. We have a huge theocratic facist base in the country that could hypothetically do more than an inept storming of the capital. Most Americans just have too much to lose to want to sacrifice themselves for their beliefs.
