Hamas (a group with terrorist elements, no doubt) killed about 400-500 military and police (legal). They killed and kidnapped several hundred civilians (war crimes). Israel killed an untold number of their own people (Hannibal directive).

In response, Israel has committed so many war crimes it would take several hours to list them all.

International law is clear: War crimes by one group NEVER justify war crimes in response.

Israel will also reap what it has sown.
