Nuclear program of Iran
U.S. President Obama reportedly sent a letter dated 20 April 2010 to President Lula of Brazil, in which he outlined a proposal of fuel swap. While expressing skepticism that the Iranians would now be willing to accept such a deal, having provided "no credible explanation" for the previous deal's rejection, President Obama wrote "For us, Iran’s agreement to transfer 1,200 kg of Iran’s low enriched uranium (LEU) out of the country would build confidence and reduce regional tensions by substantially reducing Iran’s LEU stockpile." Turkish Prime Minister Recep Tayyip Erdogan received a similar letter. A senior U.S. official told the "Washington Post" that the letter was a response to Iran's desire to ship out its uranium piecemeal, rather than in a single batch, and that during "multiple conversations" U.S. officials made clear that Iran should also cease 20% enrichment; however, the official stated "there was no president-to-president letter laying out those broader concerns".
Islamic Principlism in Iran
Various theories of state based on immediate divine legitimacy have been proposed over the years by Iranian clerics. One can distinguish four types of theocracies. Typology of the types of government adumbrated in Shiite jurisprudential sources can be summarized as follows (in chronological order):Since the election of pro-reform president Mohammad Khatami in 1997, there have been two basic approaches, two outlooks, toward the achievement of reform in Iran: "Reformists" within the regime (in-system reformers) essentially believe that the Constitution has the capacity—indeed, the positive potential—to lead the "Revolutionary" government of Iran toward "democracy." By contrast, secularists, who remain outside the regime, basically think that the Constitution contains impediments profound enough to block meaningful reform.
