There is one minor(okay, major)flaw in your post. That quote was a public quote designed to mislead the rest of the world in regard to his and the Zionist movement's true intentions. His true intentions were exposed when the private communications between him and other members of the Zionist movement were published for the world to see in the book "Expulsion of the Palestinians:The Concept of Transfer in Zionist Political Thought". Read it before you try to dispute what is in it!
