Sad but what else is new. With something like 79% of Israelis wanting this "exchange" there was little or nothing that any victim's families could have done to oppose it. I'm not a fan of ROY but this doesn't really fall on him.
When 79% of Israelis start opposing these abominations, then they'll stop. But as things stand, when Lewinsky or other PMs ask the Israeli people to jump, they ask "how high".
