This seems obvious. Children dying, anyone dying, in war is awful. Big difference, however, between targeting kids (torturing them in front of their parents before you kill them in front of their parents, sticking live babies in ovens, etc.) and being in a war where an attack kills the unintended.
Children throughout the ages have died because of their physical proximity to bad people. It’s not the same as targeting kids to torture and murder, regardless how you try and spin it.
The fact your asked twice is embarrassing for you.
