There you go again, Israel was not given to the Jews by Britain. I presume you are referring to the Balfour Declaration which talked of a Jewish homeland not a Jewish state.
Noam Chomsky makes a distinction between the concept of "a Jewish ethnic homeland in Palestine" and "a Jewish state" in a TV interview. "I have always supported a Jewish ethnic homeland in Palestine. That is different from a Jewish state. There's a strong case to be made for an ethnic homeland, but as to whether there should be a Jewish state, or a Muslim state, or a Christian state, or a white state — that's entirely another matter."
Chomsky believes the concept of a Jewish State (or Muslim State or Christian State or white State) directly contradicts the idea of a democratic state as it is understood in the Western tradition, as liberal democracy is founded upon a principle in which there is no privileged citizen. If anybody created the Israel state it was Harry Truman and George Marshall who were far more culpable than any others.
Askenazi Jews are by far the most numerous of the Jewish sects, indeed in 1931 they were more than 90% of the total, hardly a blip even in your fertile imagination.
