Pretty far, if you believe Ha'aretz's searing expose of the tactics used in the Gaza war. These are reports from the soldiers themselves, mind you:
"You do not get the impression from the officers that there is any logic to it, but they won't say anything. To write 'death to the Arabs' on the walls, to take family pictures and spit on them, just because you can. I think this is the main thing: To understand how much the IDF has fallen in the realm of ethics, really. It's what I'll remember the most."
The Times reported that the Israeli government believes it must spend more money on "hasbara," a Hebrew word that falls somewhere between propaganda and information. It is true that the world media, generally speaking, doesn't like Israel very much, and stacks the deck against it, but good hasbara starts with not allowing soldiers to vandalize Palestinian homes and shoot Palestinian women. Public relations isn't a morally relevant category, in any case: The crucial question is, how should a civilized country behave when confronting barbarism? With barbarism? Or with respect for innocent life? Pardon me for saying so, but the Jewish people didn't struggle for national equality, justice and freedom so that some of its sons could behave like Cossacks. Please don't get me wrong: I'm not equating the morality of the IDF to that of Hamas. The goal of Hamas is to murder innocent people; the goal of the IDF is to avoid murdering innocent people. But when the IDF fails to achieve its goal, and ends up inflicting needless destruction and suffering, it sullies not only its own name, but the name of the Jewish state. It risks making a just cause -- Jewish nationhood -- seem unjust, and it ultimately endangers what it is supposed to protect.
