The authors are living in an alternate reality. The facts are that Hamas holds Shalit and can demand whatever they like for his exchange. Israel's options are to take it or leave it. In five years time, Israel has not taken it or left it, but has only wasted time in demanding a bargain. It would seem that it is Israel's fantasy that eventually Hamas would cave in. There is no sign of this. The options remain the same for Israel. In time, these options will expire, as Shalit cannt last forever.
