I remember 20 years ago, during the first bombing of Gaza, they hit just ONE building and felt pressured enough to apologize for the handful of civilian deaths. Unfortunately, faced with larger threats (real or imaginary) and weak international pressure, Israel has been able to escalate the level of deterrence through the years to what we are witnessing now.
That is why any ruling to curb that "automatic" escalation (like today) is wholeheartedly welcomed.
IMO there are also subtler layers of racism coloring these policies. It's not as blatant as the far-right rhetoric, but a persistent undertone within elements of Israeli society justifies severe deterrence tactics and totally overide any empathy learnt from historical lessons.
The Israel-Hamas War is entirely a response to this event.
