Borders / Israel’s Security Barrier
In response to the second intifada (uprising), as scores of Palestinian suicide bombers entered Israel largely unchecked, Israel embarked on building a physical barrier — a fence complex in open areas, and a concrete wall in urban areas — that separates Israeli population centers from the vast majority of Palestinians in the West Bank.
The barrier’s security effectiveness is proven, but its trajectory remains a point of contention. In some cases, it separates Palestinians from lands they own and cultivate, and, notably, it divides parts of East Jerusalem from the West Bank. If the barrier were completed, it would leave roughly 8 percent of the West Bank on the Israeli side.
