In history, every time Israel has given up any area adjacent to Israel, it has resulted in aggression from that area. Conversely every area taken in the 1967 conflict and kept has not been a problem. The lesson I believe is when Israel stands strong and resolute towards its enemies nothing is lost, in fact internationally there is nothing to be lost. The vast majority of the world, even more so in Europe with its' increasing anti-Semitism, does not care about Israel. Israel only loses when it becomes forgiving of its' enemies, i.e. returning terrorists early to where they come from after imprisonment.
