In 48 hours, the islamic regime in Iran massacred more than 40,000 protestors (and left tens of thousands of people blinded/wounded, often "finishing them off" by raiding hospitals...). Some figures even show more than 40,000, but even assuming the low-park, that's 833 people per hour, or 13 people per minute who got killed.
Whatever Israel did (to defend itself) was by no means even near those numbers.
