>>>“Ubiq, do you think the chachamim would have fought the romans when they went to meet them? ”
This question wasn’t addressed to me but it seems very clearly that they would have . Chazal say that when Rav Yochonan Ben Zakai saw that those who were supposed to fighting in defense were cooking straw in boiling water for nourishment he said “could they possibly win over the soldiers of Titus ?” He therefore went to meet Vespasian. It is pretty clear that he was not opposed to their fighting per se . It was he realized it was a lost cause any way he tried to get the best deal possible.
On another note the resoyim from the Neturei Karta frequently misuse that Gemora as a justification for their being such malshinim, and mischaber and msichazek rotzchim of klal Yisroel. It is a nonsense comparison. Rav Yochonan Ben Zakai did not run a PR campaign for Titus and Vespasian, he did not enable or condone them in any way whatsoever, He basically met Vespasian under surrender terms and tried to get whatever he could for klal yisroel. The Neturey Karta for all the damage they do never ask for anything on behalf of Klal Yiroel. It’s all about their own money, kovod and achzrorius
