In the past five years Israel has mounted three major assaults on the 1.8 million Palestinians trapped behind its blockade of the Gaza Strip. Taken together, Operation Cast Lead (2008-9), Operation Pillar of Defense (2012), and Operation Protective Edge (2014), have resulted in the deaths of some 3,700 Palestinians. Meanwhile, a total of 90 Israelis were killed in the invasions. On the face of it, this succession of vastly disproportionate attacks has often seemed frenzied and pathological. Seni
