By definition, Lubavitchers cannot be Zionists.

There were 3 or 4 branches of Chabad the last of which was Babroysk. R' Kook's mother was Babroysk as was the Rogatochver and R' Zevin.

The last rebbe of Babroysk, R' Shemarya Noach, passed away in '24 or so.

R' Zevin was a Zionist. How? Because he was not a Lubavitcher but a Babroysker.

Professor Marc Shapiro: "How could you be a Zionist if you are a Lubavitcher. By definition, Lubavitchers cannot be Zionists. Today they can be practical Zionists but they can't be religious Zionists. Can't think that the state of Israel is the beginning of the redemption or anything like that and Rav Zevin thought all that stuff. Hallel on Yom Atzmut and everything because he was a Babroysker. And he had a lot of respect for the Lubavitcher Rebbe Menachem Mendel Schneerson but he did not as they say mevatel himself. He did not put away his views. Because Babroyskers were independent."
