Netanyahu Brings Fears About Iran to UN Israeli Prime Minister Benjamin Netanyahu will make his case against Iran before the United Nations General Assembly on Thursday, arguing that time is quickly running out to stop the Islamic Republic from becoming a nuclear power and the threat of force must be seriously considered. His demand that President Barack Obama declare "red lines" that would trigger an American attack on Iran's nuclear facilities has been rejected in Washington and sparked a public rift between the two leaders. But a senior Israeli official in Netanyahu's entourage said the prime minister's speech will "lay a clear red line" that will not contradict Obama's words. Israel and the U.S. have a common goal to prevent Iran from obtaining nuclear weapons. The prime minister's remarks drawing a red line will help that this is attained," the senior official said. Foreign Minister Avigdor Lieberman said this is not the first time that there have been disagreements between the positions of Israel and the United States and that this will not "in any way harm the strong friendship between the two countries." Netanyahu claims international diplomatic efforts and economic sanctions have failed. His time at the U.N. podium gives him an opportunity in front of the international community to press his case once again, perhaps in a final plea before Israel takes matters into its own hands. Also Thursday, on the sidelines of the General Assembly, key figures will gather for a Friends of Yemen meeting that will be co-chaired by British Foreign Secretary William Hague, Yemen's President Abed Rabbo Mansour Hadi and Saudi Arabia's Deputy Foreign Ministe Abdulaziz bin Abdullah Abdullah. The meeting will produce a communique aimed at generating support for Hadi, who took office in February after more than a year of political turmoil and is now trying to steer his country's democratic transition. Later, political directors from the United States, Russia, China, Britain, France and Germany will be meeting on the Iranian nuclear issue. A few hours before Netanyahu flew to the U.S., Iranian leader Mahmoud Ahmadinejad, known for past fiery denunciations of the United States and Israel, spoke at length about his vision for a "new world order" during his speech at the U.N. His speech on Wednesday happened to fall on Yom Kippur, the most sacred day on the Jewish calendar, devoted to fasting, prayer and introspection.
