Can anyone give me some mareh mekomos on the Chabad approach to Zionism / the State of Israel. From what I understand, the fifth (?) Rebbe was strongly against Zionism, but the 6th and 7th Rebbe were more pro (primarily once the State became a reality. I'm happy to be corrected though.
Secondly, is there a specific Chabad approach re the mitzva of yishuv eretz yisroel?
Thanks
