Ben Yochai witnessed the Roman annihilation of Judea. He understood that the way your enemy fights a war affects the definition of the righteous way to fight back. In other words, his recommendation was calibrated to the assumption that if the Jews are fighting a war, then their own future survival (and flourishing) is a nonnegotiable goal of the war.
Thus, a Jew living by the Torah and confronted with an enemy armed with a human shield must ask: What does God want me to do now, given what I face? And how might I figure that out by studying the Torah?
As Abraham learns when arguing with God about Sodom, the ultimate decision about who lives and who perishes in calamity is the Creator’s choice, and while you can plead with God to spare the righteous, you must also have the moral humility to trust that He knows what He’s doing.
As for you and what you can do: The Torah commands you to accept that the world’s Creator put you in the circumstances you are in, and that He only wants from you that you should do the most correct thing possible according to the Law, given the circumstances.
And among the constraints and instructions given by the Torah is a specific one: “Choose life.” Accepting one’s own death because the other options are ugly and seem heartless is not on the menu.
In the current war in Gaza, a basic Judaic question therefore arises and must not be ignored: What is the bare minimum we must do in order to prevent our own mass murder?"
nothing will change for as long as people continue to make excuses
