By Victor Davis Hanson, American Greatness - So again why did Hamas mount such a long-planned and multifaceted assault on Israeli towns, public buildings, soldiers, and civilians?... The invasion was not so much a surprise attack, in the conventional Pearl Harbor sense, as a carefully calibrated land, sea, and ground effort at mass killing and hostage taking. It was designed to execute noncombatants, grab Jews for bargaining leverage, and to shock Israelis through their pre-civilizational desecration of the bodies of the dead.
