If Britain had not supported the Zionist agenda, political immigration of European Jews to Palestine would not have happened, so there would have not been any armed struggle between Zionists and Arabs, because Zionists would have remained in Europe. Palestinian Jews would have remained a tiny minority, perhaps discriminated, like all minorities, but not necessarily persecuted or cleansed. In other words, Palestine would have been an Arab country like any other, with its (many) defects and virtues. The world in general would have been a better place, in my humble opinion.
