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".
Foreign relations of Iran
Foreign relations of Iran refers to inter-governmental relationships between the Islamic Republic of Iran and other countries. Geography is a very significant factor in informing Iran's foreign policy. Following the 1979 Iranian Revolution, the newly born Islamic Republic, under the leadership of Ayatollah Khomeini, dramatically reversed the pro-American foreign policy of the last Shah of Iran Mohammad Reza Pahlavi. Since then the country's policies have oscillated between the two opposing tendencies of revolutionary ardour, which would eliminate Western and non-Muslim influences while promoting the Islamic revolution abroad, and pragmatism, which would advance economic development and normalization of relations. Iran's bilateral dealings are accordingly sometimes confused and contradictory.
