The middle East certainly has seen it conflict before the European arrival. It also had seen long times of stability like under the Ottoman empire. In any case their conflicts pale when compared to what happened during that period on European soil. Furthermore let's not forget that our interventions have a long history. Think about the crusades and you get he idea. I personally think if we had stopped intervening on behalf of our western stooges they would have solved their problems a long time ago.  Sure there would have been human suffering along with it but not a suffering without end like i is right now.
