Vatican Swiss guards stand attention before Pope Benedict XVI delivers his "Urbi et Orbi" (to the City and to the World) in St. Peter's Square, at the Vatican, Tuesday, Dec. 25, 2012. Pope Benedict XVI has wished Christmas peace to the world, decrying the slaughter of the "defenseless" in Syria and urging Israelis and Palestinians to find the courage to negotiate. Delivering the Vatican's traditional Christmas day message from the central balcony of St. Peter's Basilica, a weary-looking and hoarse-sounding Benedict on Tuesday also encouraged Arab spring nations, especially Egypt, to build just and respectful societies.
