That's not to say that 30% isn't a crime against humanity. About 1.5 million children were murdered during the Holocaust (1.5M of 6M+ deaths). Israel murders more children than adults when compared to the Nazis.
However, from what I have observed, Israeli government officials have often expresses that intent publicly, despite claiming otherwise at the UN.
So if you optimize for collateral damage and all civilian casualties are "accidental," then you are wholly operating within the constraints of your moral framework and can plausibly deny all claims of genocidal intent.
Adult men have the highest casualties which is what would be expected since Hamas militants are most often adult men, it's well documented that Hamas also uses child soldiers to some degree as well.
> it's well documented
It's well documented that food distribution places were specifically made dangerous.
And 30% of casualties are children. The two are not mutually exclusive and this is the data point currently under scrutiny.
Cruel Israeli oppression motivates even children to resist them.
Israel then murders said children.
Obviously Hamas must be to blame for Israeli actions.
More like Hamas/UNRWA schools teach children to be terrorists.
Mobbing against Israel by Arab and their socialist friend states in the UN.
