Presidency of Mahmoud Ahmadinejad
While the U.S has linked its support for a Palestinian state to acceptance of Israel's "right to exist," Iran's President Mahmoud Ahmadinejad has retorted that Israel should be moved to Europe instead, reiterating Muammar al-Gaddafi's 1990 statement. The U.S. has sent signals to Iran that its posturing against Israel's right to exist is unacceptable in their opinion, leading to increased speculation of a U.S. led attack on Iran's nuclear facilities. Even though Iran has denied involvement in Iraq, then-President Bush warned of "consequences," sending a clear message to Iran that the U.S may take military action against it. The Bush administration considered Iran to be the world's leading state supporter of terrorism. Iran has been on the U.S. list of state sponsors of international terrorism since 1984, a claim that Iran and Ahmadinejad have denied.
Presidency of Mohammad Khatami
Khatami is regarded as Iran's first reformist president, since the focus of his campaign was on the rule of law, democracy and the inclusion of all Iranians in the political decision-making process. However, his policies of reform led to repeated clashes with the hardline and conservative Islamists in the Iranian government, who control powerful governmental organizations like the Guardian Council, whose members are appointed by the Supreme Leader. Khatami lost most of those clashes, and by the end of his presidency many of his followers had grown disillusioned with him.
