The point is to score propaganda points - there is not value to being intellectually honest in politics.

For Jews, we have to look at it from a Jewish point of view. The reasons for opposing the state at the beginning were two opposite views; the religious point of view is the Torah point of view and the holiness of the Land and the Torah Jewish connection to it. L'havdil, the Reformers were no different than the nonJeewish antisemitic views of then and now. Israel is not another piece of real estate!

"And the truth is, back then most frum Jews and almost all from rabbonim and Hassidic Rebbes were opposed to the State of Israel."

Let's not exaggerate: Going by, say, election results to the Polish parliament (both Agudah and Mizrachi were represented), at least half of religious Jews in Eastern Europe were Zionists. And many, many rabbanim- not most chassidish ones, to be sure, but many Litvish ones and even some chassidish ones- were Zionists as well. Read the account of how Herzl was received when he visited Vilna, for example. The masses turned out to greet him with awe, as did all the leading rabbanim. Outright opposition to Zionism was limited to the Brisker and some Hungarian chassidim.

The Reform were opposed to any idea of a Jewish state or any return to Zion, at least until 1937 (guess why) when they declared that going to Israel was fine for the people who really needed to. And then around 1975 they began to actively support Israel. Sure, you can question their motivations- I sure do- but they at least support it to a degree. So now we've got a bunch of Orthodox Jews who look on Israel as a compromise at best and a bunch of Reform Jews who think that it's a good thing, at least on a practical level. (Conservatism- and Reconstructionism- has always been Zionist.)
