Hakatan, as you are consistent in your views, I’ll address the American side even as R Kook is a more interesting case. R Moshe and RJB didn’t simply collaborate, they were cousins who alternated calling each other before every yomtov. Family didn’t tell RJB when R Moshe was niftar out of concern for his health, but he figured out in a month when he didn’t get a call and called himself.
