UNITED NATIONS - Hopeful yet unyielding, President Barack Obama and new Iranian President Hasan Rouhani both spoke up fervently for improved relations and a resumption of stalled nuclear talks Tuesday at the U.N. - but gave no ground on the long-held positions that have scuttled previous attempts to break the impasse.
The leaders' separate appearances at the United Nations General Assembly came amid heightened speculation about a thaw in U.S.-Iranian relations following the election of Rouhani, a more-moderate sounding cleric. In fact, officials from both countries had quietly negotiated the possibility of a brief meeting between Obama and Rouhani.
But U.S. officials said the Iranians told them Tuesday that an encounter would be "too complicated" given uncertainty about how it would be received in Tehran. Instead, Obama and Rouhani traded their public messages during addresses hours apart at the annual U.N. meetings.
U.S. President Barack Obama speaks during the 68th session of the General Assembly at United Nations headquarters Tuesday.
Obama declared that it was worth pursuing diplomacy with Iran even though skepticism persists about Tehran's willingness to back up its recent overtures with concrete actions to answer strong concerns at the U.N. and in many nations that the Iranians are working to develop a nuclear bomb.
"The roadblocks may prove to be too great, but I firmly believe the diplomatic path must be tested," Obama said. He added that he while he was "encouraged" by Rouhani's election, the new president's "conciliatory words will have to be matched by actions that are transparent and verifiable."
Rouhani, making his international debut, said Iran was ready to enter talks "without delay" and insisted his country was not interested in escalating tensions with the U.S. He said Iran must retain the right to enrich uranium, but he vigorously denied that his country was seeking to build a nuclear weapon.
"Nuclear weapons and other weapons of mass destruction have no place in Iran's security and defense doctrine, and contradict our fundamental religious and ethnical convictions," Rouhani declared. "Our national interests make it imperative that we remove any and all reasonable concerns about Iran's peaceful nuclear program."
He strongly criticized the economic sanctions that have been imposed on Iran as part of the effort to persuade its leaders to open its nuclear programs to international inspection. The sanctions have badly hurt Iran's economy, and Rouhani called them "violent" in their impact. He also said that U.S. drone strikes that kill civilians in the name of fighting terrorism should be condemned.
U.S. officials said they were not surprised to see Rouhani publicly stake out those positions on the international stage. Still, they say they see him as a more moderate leader elected by an Iranian public frustrated by international isolation and the crippling sanctions.
