regardless of who did it pulling out was a dumb thing to do because we didn't properly give the new government enough training to deal with threats like CIA
I can imagine that Germany would not have been as keen to have us occupy them if it weren't for the East-West split
typically people would be mad at a certain country for occupying them after getting rid of their leader but I could see that changing for the better or for the worse depending on how conditions changed
and as the most powerful and bountiful nation in the world bar none I don't see the situation worsening for them unless we really didn't give a stuff, which was evident in us pulling out before the situation could change for the better
really, the roots of CIA can be directly traced back to the iraq war. the problem was our action in the first place, not our lack commitment to action. once we committed, maybe we should have tried to put the pieces back together, but the answer wasn't continued military occupation. i think the very first priority should definitely be to construct a society worth keeping by developing education, healthcare, infrastructure, etc. and encouraging governments based on rule of law, not to bolster the might of a nation so it can squelch an inevitable rebellion.
at this point though, i'm not really sure what we can do. if we run in, guns blazing, and topple yet another state, what would we put in its place, and how are we going to make sure we don't just make this all happen again? we definitely need some kind of peace before any of this can even start happening though
