Sharif Hussein led the Western backed "Arab revolt". From yours truly, Syces-Picot and T.E Lawrence "of Arabia." The reason the Middle East is in shambles is because of the divide and conquer balkanization Sykes-Picot made possible. Sharif Hussein was a British agent doing nothing more than their bidding.

Palestinians are flying the flag of the revolt which brought them the Balfour declaration. In which the British gave Palestine to the Israelis. It's comically ironic. Though most of them probably don't know this and it's not really worth it criticizing it.

Almost all of Middle Eastern countries after the fall of the Ottoman Empire have a red-white-green-black flag. And they were colonized by the British. It's pretty obvious which colors they're flying.
