We wrote about him and his Etzel connections back in 2012. I guess you might say that he sold out to the Zionists he so loved. But he saw what was happening as destroying what frum Jews had succeeded in building in the Holy Land over the previous decade or so. [ He goes on to tell him how Yidden in EY are good and want to be close to the Eybershter, we just need to be mekarev them, not like the Jews from Meah Shearim who sow division, etc. ] The thousands of Lomdei Torah. The fact that every town, city and village had a Rov with a beard and peyos. That the kitchens in the IDF are kosher and closed on fast days! All this would be destroyed for one child. You can use a microscope to look at the bad, but that wouldn't be the real story, he says. He then pleads with Rav Henkin to use his influence to return Yosselle to his parents. His zeide would then be released from prison, the family would reconcile, and Yossele would eventually get a Torah education.
