I don't know what you are referring to. I suppose yet another war crime from the israeli army but this conflict generates a lot of dis/misinformation and it's hard enough to assess the trustworthiness of a source. If you don't even care to provide any source, you are just venting
It's not because you are angry about the state of the world that it absolves you of the moral duty to engage usefully with others. I know I have changed my mind on some subjects but it was never with one lazy comment like this one.
Now why is what you are talking about worse than aiming deliberately a supermarket full of civilians with a missile or hunting a grandpa with a fpv drone ? I don't really understand why you would choose to draw a line there. We already have a internationally recognized line in the sand that is somewhat actionable: War crime. It's hard to argue for genocide, it's easier to denounce and investigate suspected war crimes.
I, for one, think all war crimes are bad and should be the line in the sand where international pressure should be at its maximum.
Gaza invasion is a counterinsurgency type of war in an tighlty urbanized environment where the invader has apparently quite limited care about human life. It is not really surprising that more children would be killed there. Those are two different wars with war crimes happening in both.
