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".
Democracy in the Middle East
The current political system in Iran was designed to allow Iranians to decide their future by themselves without being oppressed by authorities, but in practice only allows a limited democracy. One of the main problems of Iran's system is the consolidation of too much power in the hands of the Supreme Leader who is elected by the Assembly of Experts for life (unless the Assembly of Experts decides to remove him, which has never happened). The power of the Supreme Leader under Iran's constitution is almost unlimited and unrestricted in practice. This combined with the view that he is the representative of God held by some religious groups, being the head of the security and armed forces, and controlling the official state media (the radio and television are restricted to state radio and television) makes him immune from any kind of criticism and unchallengeable. Critics of the system or the Supreme Leader are punished severely. Critical newspapers and political parties are closed, social and political activists like writers, journalists, human right activists, university students, union leaders, lawyers, and politicians are jailed for unreasonably long periods for making simple criticism against the Supreme Leader, the Islamic Republic system, Islam and Shia doctrines, the government, and other officials. They have been even threatened by death sentence (though all such verdict in recent years have been dropped in higher courts in recent years) and some have been assassinated by the Ministry of Intelligence and militias in the past (no such case has been reported in recent years).
