Just a few posts ago, you acknowledged that they were trying to uproot the Torah, ch”v.
Now suddenly, they’re big tzaddikim trying to save klal Yisroel? Now suddenly you don’t need a navi, you can say let’s celebrate because we know we’re better off with a medinah than without?
If you want to celebrate that we can sit and learn, have extra kavanah during Modim, particularly on Shabbos or Simchas Torah. It makes no sense to celebrate on a day when Hashem’s enemies declared war on Him. Any success we have in Torah in Eretz Yisroel is despite the events surrounding hakamas hamedinah, not because of it.
