Iran nuclear deal vindicates Rouhani\'s diplomatic push

Iranian President Hassan Rouhani's cabinet marked its 100th day Monday, riding the success of a landmark nuclear deal that has for now vindicated his push to engage with the West. Backed by top decision-maker and supreme leader Ayatollah Ali Khamenei, Rouhani embraced the agreement as a victory for Iran that has forced the world to recognize its nuclear "rights" and chipped away at punishing international sanctions. "The sanctions regime will begin to shatter with the (implementation) of this agreement," said Rouhani, of the six-month deal that aims to buy time for clinching a comprehensive accord. Under the interim deal, Iran agreed to limit uranium enrichment and curb expansion of its nuclear drive in exchange for relief from punitive sanctions and the release of some of its frozen assets. The deal marks a major, early achievement for Rouhani, who won a first-round electoral victory over a pool of conservatives earlier this year by vowing a more diplomatic approach to the West after eight years of stalled talks and escalating sanctions under his hardline predecessor, Mahmoud Ahmadinejad. Afshon Ostovar, an analyst at the U.S.-based CNA research center, attributes Rouhani's success to the realistic expectations of his negotiators and the support of Khamenei, who is the final decision-maker on the controversial nuclear program. Rouhani and Foreign Minister Mohammad Javad Zarif, who took part in the Geneva talks, "knew what could be achieved in negotiations with the West and what could not," he said. Breaking taboos, mending ties The nuclear deal came against the backdrop of a sharp turn by Rouhani away from the hostility that has often marked Iran's relations with the West since the 1979 Islamic Revolution. During a visit to New York to attend the U.N. General Assembly in September, Rouhani condemned the Holocaust as "reprehensible," after Ahmadinejad had long dismissed it as a "myth." He also broke a taboo by holding a direct telephone conversation with U.S. President Barack Obama -- the first time leaders of the two countries had spoken since 1979. The face-to-face meeting between Zarif and U.S. Secretary of State John Kerry in New York was also remarkable, and yet in the two months since then the diplomats have spent hours together in Geneva. In Washington on Sunday, a U.S. official said envoys had held "some limited bilateral discussions" since September in addition to the nuclear talks with the P5+1, which also includes France, Britain, China, Russia and Germany. The increased contacts have raised the possibility of a wider rapprochement between Washington and Tehran, fueling concerns among Iran's hardliners and in Israel and Saudi Arabia, U.S. allies who still view Iran as a regional menace. Israel and Western nations have long accused Iran of seeking a nuclear weapons capability, charges denied by Tehran, which insists its uranium enrichment program is for purely peaceful purposes. Analyst Mustafa Alani, of the Geneva-based Gulf Research Center, told Agence France Presse Arab monarchies were aware of back-channel negotiations between Washington and Tehran and "were not content." Khamenei, while backing Rouhani's nuclear negotiators, has raised concerns about the wider diplomatic push, saying at the time that "some of what happened in the New York trip was not appropriate," without elaborating. The supreme leader has also continued to wage a war of words with Israel, claiming last week that the Jewish state is "doomed to collapse." And it remains to be seen whether Iran's charm offensive will work closer to home. "Rouhani will probably want to improve relations with Saudi Arabia and other Arab states. Although this is unlikely to happen so long as Tehran and Riyadh continue to be engaged in a proxy war against each other in Syria," Ostovar said. Iran is a key ally of Syrian President Bashar Assad's regime, while Saudi Arabia, most Arab states and the West support the Sunni-led rebels struggling to topple him. "Syria will be a secondary issue, but it is unlikely that much traction will occur on that front so long as all sides in the conflict remain unwilling (to reach a) serious compromise," said Ostovar, adding that the nuclear issue will "remain central until it is solved."
