In the last decade, Israel unilaterally withdrew from two areas: the security zone in southern Lebanon and the Gaza Strip. Israel had previously withdrawn unilaterally from occupied territories without political agreements, but these two withdrawals were more significant and traumatic, both socially and politically, than any prior withdrawal. The time that has passed since these unilateral withdrawals affords us some historical perspective and allows us to compare them in terms of their outcomes and the processes they generated, both positive and negative. This perspective allows us to study the larger picture and trace influences that in the heat of the dramatic events were difficult to discern and assess.
