This image was taken from a helicopter over the frontier of Israel and the West Bank. The dividing structure is called a 'fence' in Israel, a 'wall' in Palestine (and by the International Court of Justice), and a 'barrier' in most international media outlets.
Rival claims over the same land present a zero-sum problem, which is to say anything one side gets the other side loses, unless both get nothing: zero. In the case of Palestine, the names alone indicate sharply different narratives of who is right and who is wrong. In American usage, we speak of the West Bank and Gaza Strip. In Israel, Gaza is Gaza, but the West Bank area is called by its Biblical names, Judea and Samaria. In the United Nations, the combined West Bank and Gaza are called the Occupied Palestinian Territories. All the images presented here show security forces from either one side or the other. All photos were taken by the author during an academic exchange in July 2009.
