Yosef and Rav Yosef

See here for where my father wrote about the first of the "5 derashos" of Rav Soloveitchik, where Rav Soloveitchik  reads into this week's parsha what would seem to be his own hashkafa.  Obviously, Rav Yosef Dov, cast aside by all the other Roshei Yeshiva in America was viewing himself in the place of Yosef, cast aside by his brothers.  The main thrust of the derasha seems to be that although the position of his zeideh, Rav Chaim was legitimate and possibly even correct in his stance against the Zionists, Hashem has ruled otherwise.  History has proven that it was the State of Israel that fueled the rebuild after the Holocaust, and gave Jews in America a cause to stand for and a reason to be proud.  Of course, the derasha raises the question of at what point do we say, "obviously this isn't working out.  Clearly, what we believed in is wrong."  We sometimes build towers of Torah to explain how what we believe in or want to believe in must be true, the only צ"ע is that reality seems to contradict it.  At what point must a person acknowledge the facts, see that his tune doesn't fit with the music and admit he was wrong?  Or should a person continue to insist that the facts are just an illusion, a test to your true faith, a מעשה שטן or whatever דוחק answer you can come up with to get the facts to jive with the Torah?  I leave that for you to decide.
