#1: You earlier said that there’s “quite a list of American rishwi yeshiva that got semicha from RIETS”, yet now you could only list one current such Rosh Yeshiva, when asked. (The one you mentioned is a grandson of Rabbi J.B. Solovitchik.)
The YU of today, with its toeiva clubs (since the 1990’s) and all, is incomparable to the pre/postwar period when America had very few choices of Yeshivos –and YU, with all its faults even then, was one of the only options.
