FILE - This Monday, Aug. 3, 2009 file photo released by the official website of the Iranian Supreme Leader's office, shows Iranian President Mahmoud Ahmadinejad, right, delivering a speech after Supreme Leader Ayatollah Ali Khamenei, seated at left, formally endorsed him for a second term as President during an official ceremony in Tehran, Iran. As Iran's capacity to build nuclear weapons grows, intelligence assessments from nations that follow Tehran's atomic progress discern increasing indecision and squabbling by its leadership on whether to make such arms - and if so, how overtly. Most suggest Ahmadinejad is more circumspect. But an intelligence summary shared recently with The Associated Press sees Supreme Leader Ayatollah Ali Khamenei as the more cautious of the two and says the Revolutionary Guard is benefiting from the dispute, with some of the authority normally exercised by the president devolving to it.
