hakatan, you do know that zionism existed before hertsel, right? the ramban who believed that kibbush eretz yisroel is a mitzveh never heard of hertsel who was born 600 years later. all the mamrei chazal teaching us the importance of living in eretz yisroel were written before hertsel.
what has changed is that the state was born and today it is made up of some zionists of old, some torah jews, some arabs and some goyim. if the trends continue the zionism of old will no longer be a factor in israel within one generation.
there can be no doubt that the zionists of europe(religious and not religious) were not pro-torah and perhaps in some ways ovdei avoda zuru in placing their medina as god. they tried, like you say, to eradicate by force the torah of the sfardim who came and the ashkenazim they can influence. where they made accommodations for torah it was only done in order to further their own agenda and on the theory that the torah will be lost soon. but guess what? they lost and torah won and very soon torah jews will be the overwhelming majority of the state.
