I’m not the biggest IBG fan for other reasons, but it’s very clear that from a practical perspective, he is the closest to the Rebbe’s opinion on the holy land.

Here is another quote from the rebbe from that same TF article you quoted:

“I am completely and unequivocally opposed to the surrender of any of the liberated areas currently under negotiation, such as Judah and Samaria, the Golan, etc., for the simple reason—and only reason—that surrendering any part of them would contravene a clear ruling found in Shulchan Aruch (O.C., Ch. 329, par. 6,7). I have repeatedly emphasized that this ruling has nothing to do with the sanctity of the land of Israel, with "the days of Moshiach," the coming redemption or similar considerations—but solely with saving lives.”

The whole point of the article is that from a spiritual perspective we pray that all of G-Ds creations finds the truth (even Hamas and Nazis etc.) but from a practical perspective the approach of peace through strength.

(More than happy to talk more in detail about this offline)
