If Israel is doing this to earn goodwill/approval from the international community, they are in dreamland.
I don't think that's why they are doing it. Netanyahu is no fool, he knows that no matter what he does הלכה היא, בידוע שעשו שונא ליעקב. I believe they are doing what they believe is the right thing to do, without jeopardizing security. It also plants seeds for a grassroots change in perspective (notice how many of those that find out they are in Israel are all afraid at first, and then reality hits them). It's a drop in the bucket against the overwhelming islamo-nazi propaganda, but remember what the Rebbe told Netanyahu about a small light in the midst of darkness...
