Haaretz published an analysis by an Israeli academic about a week ago saying that 61% of the deaths in Gaza have been civilians, a higher percentage, they say, than the average figure for all wars in the 20th century, and considerably higher than the figure for Israeli wars in Gaza between 2012 and 2022, which averaged 40% civilian casualties. I'd hardly describe their previous wars as 'humane' but the dramatic escalation in violence against civilians is striking and needs explanation.
It might be the case that their escalating violence will finally force major world powers (especially the US) to stop funding and arming them, but you can hardly say this is the deliberate strategy of Netanyahu et al, more just a (possible) outcome of them finally going too far.
