The war the Yevonim waged against the jews wasn’t to wipe us out physicsally. The Greeks had an agenda to transform the entire known world into a Hedonistic society. They didn’t want to kill jews because they were antisemitic and hated us. Aderabba, they let us live, as long as we accept their ways. They’d leave the Bais HaMikdash untouched, solely for its architechural ingenuities and majestic beauty. As long as no korbonos and spiritual rites were offered, and no traditional practices hinted to a Supreme Being. They even let us read the torah, as long as it was taught as a subject parallel to math and science.
The Maccabees felt this was worthy of waging a outright war and fighting for the Honor of Hashem. That meant closing their gemorahs. When the ruchnios aspect of the Jewish People is under siege, we must fight. When our PHISICAL aspect is thretened, as in the time of Purim, we fast and pray top Hashem.
The Israeli army, bless them, are fighting for our land and people which are under constant threat PHYSICALLY. Therefore there is no need to close the Gemorahs and, IY”H, our learning should stand as a zechus for the Israeli soldiers fighting, as it has since 1948.
