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".
Human rights in Iran
Iranian officials have not always agreed on the state of human rights in Iran. In April 2004, reformist president Mohammad Khatami stated "we certainly have political prisoners [in Iran] and ... people who are in prison for their ideas." Two days later, however, he was contradicted by Judiciary chief Ayatollah Mahmoud Hashemi Shahroudi, saying "we have no political prisoners in Iran" because Iranian law does not mention such offenses, ... "The world may consider certain cases, by their nature, political crimes, but because we do not have a law in this regard, these are considered ordinary offenses."
