​The study is premised on the assumption that the US-Iranian tensions under the Trump administration represents a new chapter in the crisis in the US-Iranian relationship. This extreme hostility was related to US domestic politics and the bordering on personal rivalry of President Trump with his predecessor, President Barack Obama, in domestic and foreign policy. One of the most important policy manifestations of this administrative divergence concerns the Nuclear Agreement with Iran, signed in 2015. Opposition to the Nuclear Agreement united Gulf players such as Saudi Arabia, the United Arab Emirates, and Bahrain, who considered shared hostility towards Iran as a bridge to strengthen their relations with the US on the one hand; while also forming a strong front, in the presence of Israel, to weaken the Iranian regime without necessarily replacing it.
