The facilitator for the Middle East Weapons of Mass Destruction Free Zone Conference Jaako Laajava from Finland speaks at the Preparatory Committee for the 2015 Nuclear Non-Proliferation Treaty Review Conference in Vienna, Austria, on Tuesday, May 8, 2012. Hopes dimmed Monday for staging major nuclear talks later this year between Israel and its Muslim rivals, as Iran and Arab countries at a 189-nation conference piled pressure on the Jewish state, accusing it of being the greatest threat to peace in the region. Because Israel has not signed the nuclear Nonproliferation Treaty, it was not present at Tuesday's debate. But the United States defended its ally, warning that singling out Israel for criticism diminished the prospect of a planned meeting between it and its Muslim neighbors to explore the prospect of establishing a Middle East free of weapons of mass destruction.
