I think the first thing that Blair as envoy should do is to travel throughout the occupied Palestinian territories and meet with ordinary people. He should visit the only crossing point out of the West Bank and talk to people leaving or returning, and if he still wants more he can go to Erez and realize the enormity of the tight restrictions imposed on the movement of people and goods. By simply going through the Israeli checkpoints, seeing the expanding illegal Jewish settlements and witnessing the absence of any political horizon amid the economic deprivation and hopelessness, he will know what he will need to do if he wants to succeed.
