The semenal works of Zionism and their authors?

[jimthecelt]

I am neither Jewish nor Palestinian. I am an unabashed Marxist and a friend of both the Israeli and Palestinian working classes, and I despair at their seeming inability to make common cause.
After a decades of parroting the usual cliches against Zionism, it occurred to me that I have never actually studied the movement and know nothing about it. I've finally decided to study the movement's history and ideology with an unbiased eye, something that I should have done long ago.
Who, then, were the main thinkers and theorists of Zionist theory and what are/were their best-known works? Can anybody supply me with an UNBIASED, NON-HYSTERICAL website where I can investigate Zionism's main tenants? I think that there is more to it than the simplistic sloganeering that I've heard over the years. Thanks.
