He told me that the Rebbe often spoke about conquering the world. When Lubavitchers are tots they’re taught this song, “From 770 we are marching out, on to victory there is no doubt, one by one nations we are conquering.”
It’s called לתקן עולם במלכות ש-ד-י.
Maybe the Rebbe was more actively involved in this than other gedolim.
Your claim rings similar to the Iranian and American alt-right documentaries about Chabad where they imply from the Rebbe’s sichos about Tzivos Hashem etc. that the Rebbe was secretly mobilizing a global army to fight a war against non-Jews.
Maybe join Candace Owens on her next podcast.
