No matter how sane the voices can be, the violence is going to continue. Something will give—for better or worse—eventually, but for now, we can only shout:
To the Terrorist, by definition, that innocent civilians and even children are killed isn't a regrettable cost of taking military action. It's not a cost at all. It's a benefit. It has strategic value. Goldfarb explicitly says this: "to wipe out a man's entire family, it's hard to imagine that doesn't give his colleagues at least a moment's pause."
That, of course, is the very same logic that leads Hamas to send suicide bombers to slaughter Israeli teenagers in pizza parlors and on buses and to shoot rockets into their homes. It's the logic that leads Al Qaeda to fly civilian-filled airplanes into civilian-filled office buildings. And it's the logic that leads infinitely weak and deranged people like Goldfarb and Peretz to find value in the killing of innocent Palestinians, including -- one might say, at least in Goldfarb's case: especially -- children.
