In regards to R Yosef Chaim Sonnefeld, I've always been confused by some conflicting reports regarding his role in the various nasty conflicts by the zealots of Jerusalem. In some reports, he appears as an innocent bystander, manipulated by the zealots for their purpose, in others it seems even clearer that he was a driving force behind many of the demonstrations.
The official biography of R Yosef Chaim האיש על החומה seems to be mildly apologetic. R Kook is "misguided" but R Yosef Chaim maintained a friendly relationship with him anyway. In a famous report published in R Hirschenson's Malki BaKodesh (for reasons that will become clearer in the next post) R Tzvi Pesach Frank (who was of course not an uninterested party) describes R Yosef Chaim as a pawn in the hands of the zealots.
I found another report (ShuT HaMaor Volume 2 pg. 434 a brief biography of R Bentzion Goldwicht of Montreal):
The "Rishmi HaGadol" refers to the Chief Rabbi (i.e. R Kook), According to these reports, the conflict was started by troublemakers, etc. R Sonnenfeld had the greatest respect for R Kook and only argues with him for reasons of friendship, etc.
In all this, R Sonnenfeld appears to be a moderate zealot who was "used" by the Kannoim for their purposes. In the next post, I will describe a more active role on his part.
