Thanks for this information, I'd like to offer something in return.

Only certain Hasidic groups oppose Israel, including Satmar Hasidim (over 100k followers), and Neturei Karta (fringe, only about 1k supporters). That's less than millions, and a minority within the Hasidic world.

Theologically, they oppose it based on an interpretation a Talmudic passage saying that establishment of Israel has to happen after the coming of the Messiah.

Additionally, there are a lot different denominations of Jews within Israel, some of whom have more pragmatic views. But a significant, politically influential minority believes in their duty to govern all biblical land.
