Israel has proven that international law and humanitarian law do not exist.

Yes, it's a war crime. But so is the Israeli occupation of Palestine.

Occupying a country you're at war with is OK under international law, but once you start moving your own civilian population into the occupied areas, it's a war crime. That's why Israelis settlements are illegal under international law.

Most countries have condemned Israel for their unabated war crimes for the past decades, but I dont know of any that have issued sanctions against them. Except maybe Ireland.
