Ortho, ive never heard of the sefer pirkei geulah; I’m talking about the plain reading of the rambam. I don’t care what haskamos it has; who wrote it? A Lubavitcher? It’s not in the nosei keilim or gedolei meforshei harambam – it says he will bring all of yisroel to Torah, and the Lubavitcher rebbe did not. You’re getting into hair splitting about who heard and didn’t hear of Lubavitch – who cares if they heard about it or not? More jews intermarried, regardless of whether or not their children are jewish, the point is that they left judaism entirely. The percentage of Orthodox jews, as per pew research data, was not increasing during the time of the Lubavitcher rebbe, but only started growing after his death.
And i was waiting for someone to mention putting on tefillin once as an example of returning jews to Torah. It isn’t. Because, as rav hutner explained, the rishonim are clear that in order for a mitzva to count, even according to the opinion that mitzvos don’t require kavanah, one must believe in their existence and be aware of their existence, otherwise it’s a maysoh kof b’alma. There can be no commandment without a commander, and secular jews almost universally do not believe, r”l, that Hashem gave us the commandments, or even what tefilin is, much less a mitzva. Putting leather straps and boxes on people randomly is not a Mitzvah. Actually, it can be assur if it’s done near pritzus, which often it is. And it’s also assur if the man has to use the bathroom; shluchim never, to my knowledge, ask the man if he has a guf naki, and heaven knows what kinds of hirhurim might go through his mind at the time which are a sacrilege to tefilin.
As for not needing weapons, that’s correct, but nowhere does rav moshe say that the wars are spiritual, just that the goyim will fall at his side, like they did in some of the wars fought by Yehoshua.
