Care to Share, Syag? Or are you working on Shesika?
PAA, I see how that statement about the Satan may merely mean that there is no way to say for certain that since it occurred then it must be right.
But in the same vein I do not think that Rav Soloveitchik’s statement must mean that there is proof that it was right. He was emphasizing that Hashem made it happen. It was the Yad Hashem, which is something everyone in Eretz Yisroel sees all the time, such as in the recent fighting.
