After all, those Yidden in the Midbar were probably a bunch of old fashioned fanatics, and even they celebrated the victory over the Egyptians by celebrating Of course some hareidi types object and dreamed up some argument that we should not celebrate victories on the ridiculous idea that you know who doesn’t approve of killing goyim. Those same fanatics even dreamed up the idea that the mitsva of Hanukah had something to do with some miracle in the Beis ha-Mikdash, when we all know that the thing we were celebrating was having trounced the Greeks in a good old fashioned war.
Fortunately, the Israelis have learned their lesson, and thus we celebrate military victories in honor of defeating the British in 1948, and the Arabs in 1967. Isn’t that what have a modern state is all about?
