Résumé:
Throughout history, the US-Iranian relations went through different stages; the most remarkable one was characterized by enmity and raised tensions. When talking about the tensioned relations, it is necessary to mention the Iran nuclear program as a key player. In 2008, particularly since President Barack Obama took office, he strove to improve the relations and elevate them into another level of negotiations and agreement by adopting a policy that emphasizes the importance of negotiation in order to reach solutions that satisfy both nations. Soon, events got changed when President Donald Trump took office, particularly; after the US withdrawal from the JCPOA and adopting a policy of maximum pressure by imposing tougher sanctions against Iran. Therefore, tensions started to escalate resulting to negative effects not only on the two nations but also at the regional and global levels. This work tends to investigate the foreign policies of US and Iran through the two terms of Barack Obama and Donald Trump in relation to the Iranian presidents Mahmoud Ahmadinejad and Hassan Rouhani, shedding light on Iran‟s nuclear profile and emphasizing on the main decisions like the JCPOA and its importance and effect in the direction of the relations. The study also tends to highlight various reasons that led to tensions as well as their effects on different fields.
