When my Israeli infantry unit arrived at the first village in Gaza, in July 2014, we cleared houses by sending grenades through windows, blowing doors open and firing bullets into rooms to avoid ambush and booby traps. We were told Palestinian civilians had fled.

I realized this wasn’t true as I stood over the corpse of an elderly Palestinian woman whose face had been mutilated by shrapnel. She had been lying on the sand floor of a shack, in a pool of blood.

That was my experience the last time Israeli troops entered the Gaza Strip in a large-scale way, when my special forces unit, attached to the 993rd Nahal Brigade, was one of the first to go in.

Like the invasion that the Israeli military has said is imminent, that campaign was precipitated by atrocities carried out by Hamas terrorists. On June 12 of that year, Hamas kidnapped and murdered three Israeli teenagers; soon after, Israelis murdered a Palestinian teenager. The horrific exchange escalated into a larger conflict; ultimately some 70 Israelis and 2,250 Palestinians were killed over seven weeks. Then, as now, Israelis were told that we were going in to deal a decisive blow to Hamas.
