But with US policy in the past, especially during the cold war, this was not limited to any Muslim group. In fact I'd say the Muslim groups were a minority. We got burned in Vietnam. We're in the process of getting burned by our EU "allies". We've been burned by our Central American attempts. We got burned with Cuba.
Hindsight is always 20/20, but remember at those times we had a bigger enemy which is why the US was picking the lesser of the two evils. That being the USSR at the time.
