Operation Defensive Shield (2002)
After a wave of Second Intifada bombings, Israel reoccupied major West Bank cities including Nablus and Jenin. Fighting in Jenin's refugee camp killed dozens and drew disputed accounts of a 'massacre.'
Israel regained control of West Bank cities and arrested thousands of Palestinians.
The operation reshaped Israeli control over the West Bank for years and hardened the separation between Israeli and Palestinian areas.
It is the template for large Israeli West Bank operations launched after deadly attacks, showing how one clash can trigger a broad military push into Palestinian towns.
