Synopsis

Bob Simon examines Israel's "Iron Dome," a revolutionary defense system credited by the Israeli Air Force with intercepting 85 percent of the rockets launched from Gaza into the country last November. The world’s largest civilian hospital ship delivers volunteer medical personnel to developing nations, where they have restored vision to thousands afflicted with cataracts and offered renewed smiles to those scarred by facial tumors and cleft palates.
