Hamas executed six hostages this week deep in the tunnels they dug underneath Gaza, likely because Israeli soldiers were getting too close. The most prominent amongst the bodies that the IDF brought home for burial was Hersh Goldberg Polin, an American citizen. Rachel, his mother, tried to run into Gaza last week, screaming his name with a primal, guttural cry that reverberated around the world, a mama bear searching for her stolen cub. At that point he was almost certainly alive.
