It would have been suicide to let them stay in Europe, at least in Israel they have a social and military advantage.
Many Jews stayed in Euro and lived in relative peace afterwards. The recent Anti-Jewish attacks in Europe are a direct result of Israel's actions, and Israel get's stronger for it. Jews are suffering for Zionist deeds, also why should Arabs who were minding their own business suffer for the sins of Germans? I would have support a Jewish state in Germany or Poland in a second, that's were modern Israel should be.
