TLDR, Isis is the fault of the society where it was founded, we just created a foothold they took advantage of.
I'm not disagreeing with your facts, but its always been my view that all the people who founded Isis and should be getting the MVP awards, if this is how we're talking about it now, are the Iraquies and Syrians on the ground who actually founded Isis. Sectarianism means religious war. It's a hallmark of primitive societies and shitty cultures. The MiddleEast is an unstable bloody mess, minus Israel, and it was dumb of us as a country to go poking at that mess to see what might happen. My point here is that Bush and the United States created the situation that let Isis rise, but the idea's and cultural memes that gave rise to Isis were not imported into the MiddleEast, they were and are ideas that its dictators restrain. Isis or its Christian counterpart, will not begin jestating in Kansas, because that kind of foolishness isn't represented in our society.
