2. Hamas’s use of civilian buildings changes the status of targets from civilian to military. It is vital to understand that obligations under LOAC are not unilateral and unconditional; they are often reciprocal and conditional. For example, a civilian object can be converted to a legitimate military target when used for military purposes. Even buildings specially protected under international law — including mosques and hospitals — lose their protected status when used for military purposes. So when Hamas fires a rocket from a school, or reinforces its fighters by transporting them in ambulances, that school and those ambulances become legitimate military targets. They are no longer “civilian” in any meaningful sense.
3. Hamas bears legal responsibility for civilian deaths in Gaza. Unless there is evidence that Israel clearly and intentionally targets civilians, Hamas is responsible for the civilian deaths that result from its decision to wear civilian clothes and launch rockets from civilian buildings even when Israel makes mistakes. In other words, but for Hamas’s decision to use human shields, those civilians would not be in the zone of conflict or subject to military targeting. Any other legal construct would only further incentivize Hamas’s violations of laws of war by placing on Israel an impossible burden — the burden of certainty in the face of illegal obfuscation.
