The Balfour Letter did not spring from the earth out of all context; the Ottoman Empire sided with the Germans in WWI, lost a global conflict, as well as control over their once colonies. A war weary West carved up the region, failed to recogniz undefeated men on horseback riding around dunes, and half assedly impressed a tired modernity on the unwilling vestiges of the dark ages.
But the original complaint in 1925 of the Muslim high council in Jerusalem was not 'they are taking our land!' The original complaint was "The Jews are buying our land!' -- at prices not even the sellers could afford. That is some local senitiment to get behind; "Too many Jews buying land in the 'hood."
The result was the '29 Hebron massacre, and an escalating local crap fight of violent tit for tat. The goal of British Mandate Palestine was not the state of Isreal. The goal was Palestine, where, just as in America at exactly the same time, Jews emigrated from an tribally insane Europe, where collectivist furor had succeeded in unfettering the tribe for its latest bloodletting. In America, Jews and Arabs built their homes in the same communities-- because the KKK sensibilities of "Too many Jews buying land in the hood' were at least subdued. In BM Palestine, that fine sentiment was entrenched inside the Muslim High Council.
The defensive state of Israel resulted only after WWII, long after Balfour, but directly after the entire world had demonstrated that it barely gave a flying crap about the Jews, and they were on their own in this world, as it is, to defned themselves from KKK sensibilities. So I repeat the Maxwell's demon analyis above; how is it that European Jews leaving those docks in Europe for America and Palestine managed to send all the land stealing baby killers to Palestine, and all the reasonable peace loving Jews to America, where they live in peace next to Muslims and Arabs and even the odd Welsheman doing the same? Was there an amazing 'Maxwell's Demon' at those docks, sifting humanity, that made it impossible for Jews to assimilate in Palestine as they have in America, or, once they emigrate, can they do nothing but steal land and so on, on their way to America's 51st state (Boca Raton, maybe?)
So why is it an almost autoresponse that the American left finds iteslf aligned with the interests of the Jew haters in this conflict? Because in this conflict, Muslims=poor and Jews= rich, and poor vs. rich dominates any consideration of KKK sensibilities.
It is automatic, a given. And, the reason that the history of the conflict largely ignores its roots.
Ataturk saw the writing on the wall, with regards to modernity, and brought Turkey along out of the ashes of the former Ottoman Empire. But the former Ottoman colonies, ringing the Med, were left in chaos, and modernity is still having a hard time convincing the dark agers-- the Old Men in Robes rolling their eyes over the dusty ashes of the prophet-- to call it a day. From Libya to the Balkans, same story. Former Ottoman colonies, hair on fire over the 'sudden' arrival of modernity. "What! Nobody told us!"
A war weary west in BM Palestine was saying, "Really? We need to actually prove the point with you folks? The war is over. Seriously? Modern up already. Get along. Modernity has a party it wants to throw, these sad echos from the days before domination by the Ottoman Empire, and land claims from 800 years ago, are just bullshit. Build some schools. Get busy. Trade with your neighbors, don't murder them. Buy a damn clue already. Look at the Pope; he lives in Disneyland, we gave him a nice car. He wears funny hats and waves. Everyone is happily getting busy. He's harmless. No more Crusades Do the same with your Old Men in Robes. Disneyfy them. Imagine the buses pulling into Animatronic HolyLand full of laughing kids. Sure beats the living hell out of blowing up those same busses loaded with kids over the dusty bones of the prophet and the One True Religion..."
