Chaim > The Alfandri zl who was a big mekubal in Yerushlaim said that the reaon the chafetz chaim didn’t make it to EY was because he would have made sholom between R Kook and R sonnenfeld. Had that happened moshaich would have come.
The way I read this in the (haredi Israeli) sefer, Chofetz Chaim held a more pessimistic (realitsic?): if I go first to old yishuv, then in R Kook they’ll not learn Mishna Berura, if I go first to R Kook, then in old yishuv they’ll not learn Mishna Berura. So, it is better to have Mishna Berura in Israel than me in person. Irocnically, I bought this book near rechov Chofetz Chaim in Petach-Tikva that was, I believe, named for the apartment already bought for him.
Note that Ch.Ch posted a short letter in a newspaper in Poland at a time – to respond to many letters I received, I am not going to EY this year.
