Construction Timeline: Began in 2002, about halfway completed.
Materials: Concrete walls, multilayer fences, intrusion detection, exclusion area on both sides.
Purpose: To stop Palestinian terrorists from entering Israel.
Length: 436 miles
Reaction: One of the most controversial separation walls worldwide. The Israelis see the wall as necessary to Israel's security against terrorism. The Palestinian view is that the wall cuts Palestinians off from their farmland and places of work, and confines them to specific areas. The international community, including the Red Cross, the U.N. and Amnesty International, all condemn the wall in its current form as illegal under international law.
Outcome: The wall continues to be built in spite of opposition and is expected to be completed in 2010.
