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".
History of the Islamic Republic of Iran
Following the 1979 revolution in Iran, the Islamic revolutionary regime of Ayatollah Khomeini dramatically reversed the pro-Western foreign policy of the regime it overthrew. Since then, Iran has oscillated between the two opposing tendencies of revolutionary ardour (promoting the Islamic revolution and struggling against non-Muslim tendencies abroad) and moves towards pragmatism (economic development and normalization of foreign relations). Khomeini's 1989 fatwa calling for the killing of British citizen Salman Rushdie for his allegedly blasphemous book, The Satanic Verses, demonstrated the willingness of the Islamic revolutionaries to sacrifice trade and other ties with western countries to threaten an individual citizen of a foreign country living thousands of miles away. On the other hand, Khomeini's death in 1989 led more pragmatic policies, with Presidents Hashemi Rafsanjani and Mohammad Khatami leading the charge for more stable relations with the west as well as its surrounding, non-Revolutionary-Islamic neighbors—i.e., Saudi Arabia. Following the 2005 election of President Mahmoud Ahmedinejad, Iran has returned to more a more hardline stance, frequently antagonizing the west and its neighbors while battling for control over the region.
