In this Sept. 27, 2012, file photo, Prime Minister Benjamin Netanyahu of Israel uses a large, cartoonish diagram of a bomb to dramatize his claim that Iran was 70 percent of the way to enriching uranium for a nuclear weapon, during his address to the United Nations General Assembly at UN headquarters in New York. As the meeting place for all the world’s nations and their leaders celebrates its 70th anniversary, that address is one many memorable moments in the history of the General Assembly.
