Israel and Hamas are locked again in combat likely to yield – beyond tragic life and property loss – a return to a destructive status quo. The immediate triggers were the kidnapping and murder of three Israeli yeshiva students, for which Israel holds Hamas responsible, and the revenge torture and murder of a Palestinian teen by vigilante Israeli Jews. The nature and extent of Hamas’s involvement in the initial obscenity remains unclear, but the attack’s consequences are anything but. Since Israel launched Operation Protective Edge on 8 July, 168 Palestinians have been killed (80 per cent civilians, a fifth of whom were children) and about 1,150 wounded. Some 1,000 rockets have been launched toward Israel, of which about 200 were intercepted by the Iron Dome defence system. Previous rounds ended with each side claiming at best a Pyrrhic victory, because Israel can achieve lasting stability only when Gaza does, and vice versa. Breaking this pattern is even more urgent today, because the stakes of this escalation could be higher.
