We also have to remember that prior to 1917, in order to get their cooperation, The British and French promised various Arab states land and independence after the fall of the Ottomans. Only to THEN turn around and form the Sykes-Picot agreement divvying up the land amongst themselves. This is where the idea of a Zionist state first began to be discussed and various Arab groups were betrayed to make it happen.
I’m not saying terrorists aren’t evil. But everything in the middle east is the result of “the west” fucking the people over there over for more than a hundred years.
