"Hell on Earth"

I have just had a rather loud and fractious debate/argument with my brother over Israeli aggression in Gaza. More than 800 palestinians have died since Israel's military offensive began on Dec 27 last year, a good fraction of them innocent children, compared to 13 on the Israeli side. My God-fearing brother considers the casualties to be collateral damage. He chooses to put the blame squarely on Hamas for the firing of rockets, completely disregarding the disproportionate use of force. I wonder how many in his church congregation share this viewpoint. I wonder if his views have been shaped somewhat by his religious convictions.
