All reasonable people, Dershowitz argues, know what a final peace settlement will look like: two states, based on Israeli withdrawals from Gaza and most of the West Bank; a symbolic recognition by Israel of the rights of Palestinian refugees, with some compensation but no "right of return"; the division of Jerusalem; and a renunciation of violence, with the Palestinians taking all reasonable measures to stamp out terrorism. The problem is how to get there without more bloodshed. To that end, Dershowitz identifies twelve geopolitical barriers to peace--and explains how to move around them and push the process forward.
