Let it be clear that Zionism and Judaism are different things. The practice of this ancient and respectable religion has nothing to do with the ideology born in Europe at the end of the 19th century.
Zionism comes from no other source except from Judaism! Open up the holy book of the Jews and you will see that what the Jews are doing in Palestine is exactly what they are told to do by their holy book. David Ben Gurion said that the Bible is his mandate and the British mandate, he said, were obeying what is written in the Bible.
