During the 1980s, Iran and the US engaged in a bitter conflict known as the Iran-Iraq War. The US supported Iraq in this war, providing intelligence, weapons, and financial assistance. Iran, in turn, accused the US of supporting terrorist groups in Iran and Lebanon, including the Islamic Revolutionary Guard Corps (IRGC).
In 1983, the US Navy shot down an Iranian civilian airliner, killing all 290 passengers and crew on board. This incident further strained relations between the two countries and led to increased calls for revenge.
In 2002, the US accused Iran of developing nuclear weapons and labeled it as part of an "Axis of Evil" along with Iraq and North Korea. This accusation further heightened tensions between the two countries and led to the imposition of economic sanctions on Iran by the US and its allies.
In 2015, Iran and the US reached a historic agreement, known as the Joint Comprehensive Plan of Action (JCPOA), aimed at limiting Iran's nuclear program in exchange for the lifting of economic sanctions. However, in 2018, the US unilaterally withdrew from the JCPOA and re-imposed sanctions on Iran.
Since then, relations between Iran and the US have deteriorated further. The US has imposed additional sanctions on Iran, and Iran has responded by reducing its compliance with the JCPOA and threatening to close the Strait of Hormuz, a vital oil shipping route in the Persian Gulf.
In January 2020, the US assassinated Iranian General Qassem Soleimani in a drone strike near Baghdad. This act further increased tensions between the two countries and brought them to the brink of war.
The relationship between Iran and the US remains highly volatile and uncertain. Both countries have expressed a willingness to negotiate, but there are significant obstacles to overcome, including mutual distrust and the complex regional issues that have intertwined their interests and conflicts. The future of their relationship remains a source of concern and instability in the Middle East.
