@qwerty the rebbe has thousends of sichos. there are almost 200 volumes printed of the sichos he said. you are right he said many many times that ALL jews will be redeemed. in his printed sichos there are sources for everything. check there. anyway in 1943 ?’ ??? ????????? sent a letter to the rebbe with the following question: ????? ?????? ???, ?”? ?????? ???”?, ?? ??? ??????, ???’ ?? ????’, ?????? ??? ???? ?? ????, ?”?, ?? ?? ????. ???? ???, ?? ?????? ?? ?? ??? ???’ ??????, ????? ?? ???? ????, ????? ???? ????? ?????? ??? ???? ???, ??????? ???? ??? ??? ?????? ?? ???? ??????, ?? ??? ?? ??? ??? ?????? ????? ?????? ???”? ?”?.
??????? ????? ????? ?? ?????, ???? ?????? ?”? ?? ????? ?????”?.
the rebbe responded with a 13 page letter (printed in igros kodesh vol 1 letter #85) going thru all the gemaras and other sources and explaining them
(in those days people had the decency to ask if they had a question rather than attack, as the rebbe was knows by all to be one of the greatest gedolim alive. for example rav hutner wondered about the rebbe’s idea to put tefillin on jews, so he wrote to the rebbe to explain some questions he had about it (find it in ???? ???? ????) (even R shach sent someone to ask a question to the rebbe about something in kabala because he didn’t know, and knew the rebbe would know – i thing yeshiva wold wrote an article about it)
