Opposition leader, Tzipi Livni, stated Wednesday at the Conference of Presidents in Jerusalem that "rejection by Iran of the world's demand to cease uranium enrichment should lead to the understanding that Iran is playing with the world and buying critical time to acquire the bomb. The world must stop Iran now using harsh and effective restrictions - with or without consensus."

"The Iranian threat is not just a matter for Israel, despite the direct threats and despite the Holocaust denial of the Iranian leaders. Its clear today that the world can not afford a nuclear Iran, and she must place all the options on the table," Livni added.
