“Lubavitch was the only Torah outreach movement. (Not anymore today bh)”
I have a different perspective on this point.
After the war most of the Gedolim in E”Y and America where focusing on rebuilding Yeshivos and Beis Yaacovs. This is very much in line with the priorities expressed by ריב”ז when he famously asked for Yavneh and it’s scholars. This was a two pronged project. (1) The establishment of major Torah centers and (2) the establishment of day schools and later kollelim in many “out of town” communities. Their efforts where blessed with tremendous success and today we are all the beneficiaries of their foresight and mesiras nefesh.
I think you would be hard pressed to demonstrate that the last Lubavitcher Rebbes shlichus initiative had a greater overall impact on Klal Yisroel.
But I digress. I will be happy to address the other question shortly.
