You mention the Bilu'im as well as the other Chalutzim who weren't religious. I have news for you. Of the three thousand students who came to become Jewish peasants, as it were, half of them returned to Mother Russia after a while. What is more interesting is what the official historians forget to tell us, of the ordinary Russian Jews who reached Jaffa and Haifa in during the Second Aliya because they didn't have what to pay for the trip to America--Hovevei Zion gave them their ticket and they were on their own when they got to the Land of Israel. Those mostly Halachically Observant Jews who arrived and were responsible for the hundred thousand Jews who comprised the basis for the claim for a Jewish entity in the Land of Israel. In fact, they called for a rabbi, whose name was . . . Rabbi Abraham HaCohen Kook. The Chalutzim were a minority off in the boonies. Without the Tzibur Dati and Mesorati of the New Yishuv, the Balfour Declaration would have been a "scrap of paper".
