The Nissim shown in the Israeli wars are no less than the many Nissim we relate of what happened throughout the generations. The Nissim we see daily might even be greater since it is continuous. Of this it is said Ke’ilu Yesh Lo Eloka. It is visible that we have Someone protecting us.
Why should we be Kafoiye Tov, especially Beshita? In fact, the arguments to explain away the events don’t sound much different from any athiest explaining all the Nissim we all agree to. Descriptions of Yetzios Mitzraim in many encyclopedias sound just like the founding of Israel. It is scary to me, hearing this type of thinking in our midst. This is the real edited training.
On the other hand it is ignorant to think this is the first Ness we’ve had since Chanuka. What about where Rebbe Shimon got rid of evil Roman decrees through a miracle? What about when Rabbeinu Hakadosh miraculously showed up to the kaiser and averted a catasrophe? Should we declare a holiday the day the Amshinover Rebbe told the Japanese why the Germans hate us?
It would have been very appropriate to thank Hashem at the time, publicly. Perhaps designating a day to add some Tehillos would also be nice. But adding more significance to that than a Hillula is obviously just out of the nationalism of which, as we know, many were opposed.
