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.
Nuclear program of Iran
On 2 February 2013, speaking at the Munich Security Conference, U.S. Vice President Joseph Biden said that the Obama Administration "would be prepared to meet bilaterally with the Iranian leadership. We would not make it a secret that we were doing that. We would let our partners know if that occasion presented itself. That offer stands, but it must be real and tangible, and there has to be an agenda that they’re prepared to speak to. We are not just prepared to do it for the exercise." A few days later Iranian supreme leader Ayatollah Ali Khamenei rejected the offer and added ambiguously: "The U.S. policies in the Middle East have failed and the Americans are in need of a winning hand. That is bringing Iran to the negotiating table." On 4 February the Italian news-wire "Agenzia Nova", citing "sources in Teheran," reported that "from the beginning of the year Ali Larijani, Speaker of the (Iranian) Parliament, secretly traveled twice to the United States" to launch direct negotiations with the Obama Administration. The Italian Agency explained that U.S. diplomacy was waiting for the Presidential election in Iran, that most probably will see a dramatic change in Iranian approach. It was reported on 17 June Iran’s newly elected president Hassan Rohani had expressed readiness for bilateral talks with Washington, with conditions.
