Foreign policy of the Mahmoud Ahmadinejad administration
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.
Iran's 2018 lawsuit at ICJ against the United States
US President Donald Trump pulled out of a 2015 accord between Iran and "major world powers" whereupon some of the sanctions against Iran were lifted in exchange for Tehran accepting some limitations on its nuclear program. The US government then announced "unilateral plans" to re-impose sanctions against Iran. The Iranian government believed that the United States’ decision on 8 May 2018, to re-impose nuclear sanctions on Iran was a violation of the United States' international obligations, "especially articles 4, 7, 8, 9, 10" of JCPOA and the Treaty of Amity. Consequently, Iran filed a lawsuit with the International Court of Justice on 16 July 2018.
