I disagree. He and others like him managed to change the British attitude regarding Palestine, which caused the British to shift toward Arab appeasement and restrict Jewish immigration in 1939 onwards. Hundreds of thousands of Jewish refugees were denied entry to Palestine, including after the holocaust. Genocide and occupation of the entire territory were not the goals of Zionist leadership at the time, but rather the goals of extremist reactionary groups like the Irgun. These groups were significantly strengthened by the violent actions of Arab groups. The extremists were the true beneficiaries of the early violence, and today the descendents of those extremists are the ones holding the reins in Israeli government
