Sorry to interject again. One must remember that Zev Jabbotinsky did travel through Europe trying to get people out during the days prior to and during his foundation of Batar. He was VERY anti-Socialist/Communist which Begin and Shamir both note in their memoirs which was the reason why he and Weismann had such heated debates. Weismann, left the call to get Jews out of Europe to invent military weaponry for the allies.....and thus making comments about leaving the Jews to be "the dust of history". ("the Transfer Agreement", "While 6 Million Died") Jabbotinsky stayed and tried to rally some Jewish Nationalism, not secular Zionism of Weismann. Jabbotinsky, from what I am given to understand, had much against him since many of the Jews of Eastern Europe turned to Socialism/Communism: Bund due to years of Czarist pogroms. That said Jabbotinsky had the Socialist Judenrot undermining him on one hand and the Hassidim undermining him as a crack pot on the other because he was not religous and not Hassidim....("Years of Wrath Days of Glory")
An interesting fact to note is that in the late 1870's-early 1880's prior to Hertzel, Jabbotinsky, Weismann etc. there was an Orthodox Rabbi from Lithewania, I believe but not 100% sure, that preached "Religious Zionism" on similar scales of Rav. Kahane. His name was Rav. Samuel Mohilever. The Head Rabbi of France introduced this different type of Rabbi to Baron deRothschild, an Orthodox Jew, in September '82 to drum up support and financing of Jewish settlement in "Palestine" for the suffering Jews of Eastern Europe. ("The Rothschilds"-Frederic Morton) This was, from what I have read, the start of modern religious Zionism which had only a few years later been highjacked and crushed but the wave of Labor "Zionism": Socialism Alyiah to Zion to set up a Jewish Socialistic "Utopia": The modern Bolshevik state of Israel today... (From what I have read......)
PS: One can note very precisely that ever since the 13th century there has been a steady stream of Jews returning to Zion which is perhaps the reason why Mark Twain noted in his 1860's "The Innocents Abroad" of not seeing any "Palestinians", a very few Mohammedans West of the River Jordan but many religious Jews.
