One of the major theological controversies in recent years has been the validity of the Satmar Rebbe's claim that the Six Day War victory was ma'aseh Satan and whether miracles only happen to frum people. [There is of course Rav Moshe's teshuva (Y.D. 4:8.2) regarding the miracle of Entebbe which clearly disagrees with the Satmar. ] But there is a little known or remembered event that happened shortly after the Six Day War which clearly defined the basis of dispute. This is the version I heard from Rabbi Gavriel Beer - a life long Aguda askan - who was there.
As is well known by now, the mood leading up to the Six Days War was very gloomy. Many in Israeli and in the Diaspora were anticipating a war which would be very costly in life - both for the soldiers and civilian population. The more optimistic view was that Israel would take a harsh beating but would survive. There is no need to mention the pessimistic view.
But when the guns were silent after the incredibly short war in June 1967, Israelis discovered that not only had they survived but they had soundly thrashed the massive armies of the surrounding Arab countries and in addition had acquired the West Bank - which included the Old City of Jerusalem and the location of the Temple. Everyone seemed to say it was an open miracle. There was one major dissenting voice - the Satmar Rebbe - who insisted that it was not only not a miracle but the victory was in fact the work of Satan. He emphatically stated that miracles don't happen for the Zionist - especially to support the theological crime known as the State of Israel.
Several months later at the annual Aguda Convention, this astounding event was the central topic of discussion Speaker after speaker spoke on the topic and the gedolim were clearly divided on whether to agree or disagree with the Satmar position. One of those who publicly agreed with the Satmar view was Rav Yaakov Kaminetsky.
At the Melava Malka that weekend, the keynote speaker was Rav Itchie Meyer Levin - the Gerrer Rebbe's son-in-law. He of course spoke about the topic. After some introductory comments he made the following observation. "Not so long ago the Jewish people suffered the horrible loss of 6 million Jews in the Holocaust. When we went to the gedolim for an explanation we were told that we must be silent and accept this because it was G-d's will. Now we were just faced with another possible holocaust in the Land of Israel but the Jews were saved this time. We hear gedolim who say that these millions who were saved were saved by Satan. How is that when it comes to the death of Jews it is G-d's work but when it comes to rescuing them from death it is Satan? It can't be."
In response, Rav Yaakov Kaminetsky quickly wrote a note which he sent to be read from the podium. It said, "I want to publicly retract my previous statement supporting the view of the Satmar Rebbe and say that now I agree fully with what Rabbi Levin just stated."
Rabbi Beer noted that this was Rav Yaakov's greatness. His only concern was truth and he wasn't afraid to publically admit that he had erred.
======================
Igros Moshe(Y.D. 4:8.2):Concerning the matter of the Jews who were hijacked in Uganda and then were saved by [Israeli] soldiers who went to Uganda. It is reasonable that this should be considered an open miracle. That is because in the normal course of events it would not be possible that such a thing be successful. Whatever is done in the world is only by the hand of G‑d – whether it is for the good or whether it is – G‑d forbid - ! the opposite. He causes the blow and the cure. He caused that these Jews be captured. But He also caused that they were rescued by means of giving these soldiers special courage and motivation so that they were able to save the captives. He also arranged circumstances so the soldiers in fact were successful. Nevertheless the reasons that G‑d did a miracle through sinners are hidden from us. Furthermore it is prohibited for any man to be “wise” and raise question against G‑d’s actions. Rather it is necessary for us to be innocent and accepting whatever G‑d does as it explicity says in the Torah (Devarim 18:13)
