The majority of deaths in Gaza are women and children. Nearly 70%.[1] The reason we talk about "women and children" in Gaza is because Israel can accuse any adult man of being a militant. Statistics from Ukraine are harder to get but according to the OHCR,[2] we know that 39% of non-combatant casualties are women and less than 5% are children. What percent of total deaths are civilians is the hard part, but in Donbas about 25% of casualties were civilian.[3]
(.39 + .05) * .25 = .11
So we have a 70% women/children rate vs about a 11% (very very roughly calculated) women/children rate. Yes the nature of these conflicts are extremely different.
Sure. This is how "comparing it to the war in Ukraine" is both helpful and informative.
