“No other country uses roof-knocks, a munition developed by Israel as part of a series of I.D.F. warning procedures…”

The report acknowledges that Israel took steps to warn of imminent attacks but suggests more should have been done to minimize civilian casualties. Yet it offers no opinion about what additional measures Israel could have taken. It even criticizes Israel for using harmless explosive devices — the “knock on the roof” — as a final warning to evacuate targeted buildings, suggesting that it created confusion. No other country uses roof-knocks, a munition developed by Israel as part of a series of I.D.F. warning procedures, including text messages, phone calls and leaflet drops, that are known to have saved many Palestinian lives.

Judge Davis suggests that the I.D.F.’s use of air, tank and artillery fire in populated areas may constitute a war crime and recommends further international legal restrictions on their use. Yet these same systems were used extensively by American and British forces in similar circumstances in Iraq and Afghanistan. They are often vital in saving the lives of our own soldiers, and their curtailment would jeopardize military effectiveness while handing an advantage to our enemies.

The I.D.F. is not perfect. In the heat of battle and under stress its commanders and soldiers undoubtedly made mistakes. Weapons malfunctioned, intelligence was sometimes wrong and, as with all armies, it has some bad soldiers. Unnecessary deaths resulted, and these should be investigated and the individuals brought to trial if criminal culpability is suspected.
