A key defense of powerful nations that terrorize with their military is that civilian casualties are unavoidable because the real terrorists fight dirty using hostages. When Israel besieged Gaza last year they alleged that Hamas was using mosques and hospitals and schools as weapon storage lockers and stuffing them full of civilians in order to incite international outrage when Israel bombed those sites. According to the UN this was a lie. When Israel bombed these locations, the civilians were there, yes, but not the armaments.
Ken Silverstein interviews "Desmond Travers was one of the four members of the United Nations Fact Finding Mission on the Gaza Conflict, which produced the controversial Goldstone Report":
We found no evidence that Hamas used civilians as hostages. I had expected to find such evidence but did not. We also found no evidence that mosques were used to store munitions. Those charges reflect Western perceptions in some quarters that Islam is a violent religion. Gaza is densely populated and has a labyrinth of makeshift shanties and a system of tunnels and bunkers. If I were a Hamas operative the last place I’d store munitions would be in a mosque. It’s not secure, is very visible, and would probably be pre-targeted by Israeli surveillance. There are a many better places to store munitions. We investigated two destroyed mosques—one where worshippers were killed—and we found no evidence that either was used as anything but a place of worship.
So Israel's justifications for targeting these locations proves to be baseless. Will people stop screaming "anti-semitism" now every time the subject of war crimes comes up in relation to Israel? Probably not.
Here's the thing about the hostage argument: if a madman is holding hostages in a building the solution to the problem is never going to be to bomb the building. Negotiate. Wait them out. Prepare to pounce when they make a mistake. Do not, under any circumstances, start lobbing grenades into the room with the hostages! Hamas was not holding hostages, but even if they had been it would be unconscionable that Israel launch an assault under those circumstances.
Yes the terrorists fight unfairly. Sure their tactics are designed to inflict maximum international pressure on Israel. So why give them more ammunition by bombing mosques and hospitals? It just proves there are two madmen in this situation and they are holding everyone else hostage between them.
