You mean behave like the US, who when they got hit by a terror attack, stomped two countries flat, one of which hadn't anything to do with it? Behave like you who regularly kill bunches of civilians with drones in Afghanistan and Pakistan, and no one whines about war crimes? You know what? Maybe Israel should take the gloves off, like you all when you're hit, since I notice the world doesn't say much about America's kind of warfare. Thanks for the hint.
