Iranian President Mahmoud Ahmadinejad (r.) is escorted by technicians during a tour of the Tehran Research Reactor center in northern Tehran, Iran, on Feb. 15, 2012. Iran denies that it aims to produce nuclear weapons, with Supreme Leader Ayatollah Ali Khamenei calling them unIslamic and a 'sin.' But inspectors of the UN’s International Atomic Energy Agency (IAEA) say they still have questions about possible past weapons-related work, and want access to a military base at Parchin.

An Iranian ballistic missile is launched during maneuvers by Iran’s Revolutionary Guard at an undisclosed location in Iran, July 3, 2012.

An Iranian policeman walks past the car belonging to Iranian nuclear scientist Mostafa Ahmadi-Roshan at a blast site outside a university in northern Tehran, on January 11, 2012. Ahmadi-Roshan was killed by a bomb placed on his car by a motorcyclist in Tehran, one of five Iranian scientists connected to Iran’s controversial nuclear program to be assassinated in the last two years. Iran blames the US and Israel for the killings, as part of a covert war aimed to slow its nuclear work. Sajad Safari/IIPA/AP
In this satellite image supplied by the Institute for Science and Security (ISIS), two buildings appear to be shrouded in pink tarps that ISIS says is to stop the UN nuclear agency from monitoring Iran's efforts to sanitize a site they suspect was used for weapons-related work, in this photo dated August 15, 2012, of the Parchin military complex southeast of Tehran, Iran. Previous photos taken earlier of the same site appear to show the same buildings, without a tarp and with extensive alterations undertaken as the suspected high explosives testing. The UN's International Atomic Energy Agency (IAEA) has requested immediate access to the site, but reported in late August that the apparent sanitizing had 'significantly hampered' the IAEA's investigation.

Israeli analysts, however, say that the election of a more moderate president in Iran will force Israel to adjust its public posture on the Islamic Republic.
For years, Iranian President Mahmoud Ahmadinejad spooked Israelis with talk of wiping the Jewish state off the map. But the victory of Hassan Rohani, known as a moderate, could pose an even bigger challenge for Israel, analysts say.
