In the following video, David Icke does an excellent job explaining the fundamental relationship of the Rothschild dynasty and their secret societies to the Zionist state of Israel. This is a very important aspect of Zionism that very few are willing to talk openly about as Icke does here.
If anyone doubts the essence of what David Icke discusses in this video, I would suggest getting a hold of the two volume set of The Encylopedia of Zionism and Israel and reading the articles about the Rothschilds and those on the secret societies of the B'nai B'rith and the B'ne Moshe.
These articles explain how the Rothschilds funded secret societies to foment Zionist fervor in the Pale of Settlement and how the political ideology of Zionism was grafted onto orthodox Judaism in Poland. The articles on the first Rothschild settlements in Palestine are also essential reading.
