Are they kidding? Anybody trying to leave would be shot...in the back by the Palis. This guy was also probably shot by them to make the Jews like bad. Remember, the Muslims hate the Christians as much as they hate the Jews, and this man was a Palastinin Christian. That makes him a traitor to Muslim.
Generally true but the Jews and Turkish Muslims have a strange love affair going back to the time the Turks conquered Christian Byzantium. The Turk allowed Jews from Spain to settle in the newly acquired Ottoman Turkish imperial lands often allowing Jews to take over formerly Christian homes and land. For example, there are letters from Jews to the Turkish pasha asking for Christian slaves to be sent to him to work in his operation in N. Africa.
Don't get me wrong - the "love" affair that some Arab Christians have with their Muslim cousins is just as strange...maybe some psychiatrist can explain that.
