I take all of this with a grain of salt. I have seen this video before actually. I'm pretty sure it was made by Rabbi Amnon Yitzhak, although I'm not sure. In any case, it is clearly an anti-zionist polemic and it utilizes some arab-loving sources for its "dirt" on the antireligious aspects of the founders. Given that Rabbi Kahane's father had a personal friendship with Jabotinsky and held him in highest regard, and Rabbi Kahane himself never slung mud or attacked the foundations of Jabotinsky, I find it hard to believe that a snippet here or there from his diary is representative of his views as he matured in his beliefs over his lifetime or that his philosophy was as the film makes it out to be... Otherwise how could these great men promote him/them and honor his/their memories? Something doesn't add up.
