The European Jews used to live in the ghettos of Eastern Europe, a very poor and a very hungry people, and then they got transplanted on to Palestinian soil and the Jews all over the world benefited from this transplantation. If the Arabs were to succeed in getting rid of them from Palestine, the fortunes, power and prestige of the Jews of the world will also go tumbling down and therefore they will do anything in that power to prevent from being thrown out of Palestine!
