PARIS (AFP) - The West on Saturday was guarded about the landslide re-election of leader Mahmoud Ahmadinejad as Israel said the victory proved the Iranian threat had grown. There were no immediate reactions from Western governments but former leaders and opposition politicians were cautious in their responses. Ex US president Jimmy Carter said there would be no change in American policy because the same person will be there in brief remarks after he met Palestinian officials in the Israeli-occupied West Bank. In Moscow, the chairman of the Duma (parliament) Committee on International Affairs Konstantin Kosachev said he hoped Ahmadinejad would show more understanding and wisdom towards the international community during his second term. In Jerusalem, Israels deputy foreign minister expressed disappointment at the defeat of moderate ex-premier Mir Hossein Mousavi. The results of the election show, now more than ever, how much stronger the Iranian threat has become, Israels deputy foreign minister, Danny Ayalon, said. The United States said it was monitoring reports of irregularities in Irans hotly contested presidential race. Like the rest of the world, we were impressed by the vigorous debate and enthusiasm that this election generated, particularly among young Iranians, White House spokesman Robert Gibbs said in a statement. US Secretary of State Hillary Clinton expressed hope the Iranian presidential vote would reflect voters will. We hope that the outcome reflects the genuine will and desire of the Iranian people, Clinton told reporters on a visit to Niagara Falls, Canada. US President Barack Obama has vowed to pursue diplomatic engagement with Tehran in a bid to convince the Islamic republic to stop sensitive nuclear work the West fears could hide efforts to build atomic weapons. The Arab League urged Ahmadinejad to use his re-election to resolve the nuclear issue and establish peace and security in the Middle East. We hope to work together to achieve regional security through ridding the Middle East East of weapons of mass destruction, said Arab League chief Amr Mussa, according to Egypts MENA news agency. Syrias President Bashar al-Assad, in a message, stressed the need for the two countries to work together to achieve lasting and comprehensive peace in the region and the world, the state-run SANA news agency said. Venezuelan President Hugo Chavez telephoned Ahmadinejad to congratulate him, telling him the victory represents the feeling and commitment of the Iranian people to building a new world.
