I don't know, but he has been praising the Satmar rebbe, and saying that Satmar love him, so it's not impossible that it's related. He said that you aren't allowed to live in Judea and Samaria, that Arabs have the merit to stay in Israel, that we can give land and it doesn't matter because G-d will give it backs if we deserve it, being the incorrect, in my opinion, judgments on his teachings, and the only correct one I know of is that not all Jews really do go to heaven. I've never heard him attacking him directly though.
