David Harris-Gershon grew up regarding Palestinians as the enemy: “They were just the latest in a long line of people wanting us dead, lined up throughout history: Arabs, Germans, Russians, Romans, Greeks, Persians, Babylonians, Egyptians.” So you might think a Hamas-orchestrated bombing in Jerusalem that left two of his friends dead, his wife badly injured and him with a nasty case of PTSD would only harden those feelings. Instead, it led to a re-evaluation, a visit to the bomber's family and a more complicated view of the Israeli-Palestinian conflict. David and I talked about his new memoir and his change of heart.
