MW,
He was not opposed to certain bochurim who were really not being successful to the extent that they were at risk joining Nachal Chareidi, as it was the understood to be set up.
His shitta was different in that he agreed that there were LIMITED situations where one can join the IDF.
However he never suggested that that All Chareidim should be responsible for some service (meaning army or ????? ?????) which is what ZD suggested.
Nor did he ever say that ??? ???? was a ??????? for anyone.
Which is completely different than what ZD attitudes to R AL Shteinman.
