The Vayoel Moshe is very strongly against both settling in Israel and cooperation with the Zionists. Yet The Satmar rebbe zt”l himself tried moving to Eretz Yisroel twice- once in the 30’s in attempt to take over the Eida Chareidis from Rav Dushinsky, and once after the war to establish a new kehilla. As well, he cooperated with the Zionists to leave Hungary. So quoting the Vayoel Moshe as THE authoritative viewpoint when its author clearly didn’t think so it a bit sketchy.
This isn’t to whitewash the sins of the Zionists, to be sure. They were reshaim.
