Andrew Sullivan highlights this story in Susan McGregor’s report on the peace processes and technology. It’s told by Jimmy Carter describing the final days of the Camp David accord between Israel and Egypt:
Three days before the accords were signed, Israeli Prime Minister Begin announced that he would be withdrawing from the negotiations. He had taken an oath that he would never dismantle an Israeli settlement, and the discussions had reached an impasse. Before departing, he sent eight photographs to Carter for his signature: commemorative photos of himself with Carter and the Egyptian President Sadat. Later that day, Carter personally delivered the photos to Begin, each inscribed with the name of one of Begin’s eight grandchildren, as well as the president’s signature.
Begin, moved to tears by the personal gesture, agreed to return to the negotiating table.
