At the end of the second world war, while British troops were liberating Jews in German POW camps, Jewish guerrilla and terrorist activity was directed against British servicemen, not the Arabs.
Harried by criticism from Washington and American public opinion, Churchill responded by offering that the U.S. take over Palistine. And, although the U.S. voiced its support of a Jewish state it didn’t take up the challenge. By February 1947, the British Government had no option but to abandon its commitment and return Palestine to the United Nations who separated the land into Arab and Jewish states. The British troops withdrew from Palestine by May 1948 and the inevitable Jewish-Arab war that followed resulted, and the state of Israel emerged victorious.
Your history lesson is one-sided and simplistic. Treatment of history as black and white, right and wrong produces a pi$$ poor assessment of the facts. Try to answer these - when China becomes the superpower, how will it write the history of the U.S.? Will the U.S. become more or less repugnant than the British you portray?
I am not psychic, so I have no idea IF China will become "the superpower", let alone what histories they might write or how they might characterize anyone, were all that conjecture come to pass. And neither does anyone else.
I am old enough to remember the period between the liberation of the camps and Statehood and all the history in between and since. I met some of the men who fought in the 1947 war and some of those who came directly from Europe to Israel. They were there. So was I. My family was friends with Israelis in the 1940's & 1950s. Many histories document what happened. You may choose to read them selectively, if you wish. I stand by my statements.
