Oh, I totally agree.
The English Bureaucraps really screwed things up in the Middle East. How they handled the dissolving of the evil Ottoman empire is what created the divides within the Kurd people. They are so very different from 1 country to the next. I think it is because of where they were situated and that there are so many natural resources collected there. If you want to see why the English did what they did, follow the money (some of it oil money).
And never forget the effects of the Genocide in Turkey and the region. That drove dissimilar people into Northern Syria trying to survive. That is why they get along better in Northern Syria than in other places. They were forced to cooperate and get along to survive. That is a great cultural cement.
