Is your impression that that's what Hamas is accomplishing?

I don't know what the hell else the Gazans could do, no one's helping them and they are dying. But there is a reason Israel was making sure Hamas was getting funding for years and years and supporting them against domestic opposition: Because what they're doing doesn't work, except to provide additional excuses for Israel to keep mowing down villages. If what they were doing worked, Israel wouldn't let them do it.
