This report analyzes the prospects of the Caspian Sea region — and its key actors except for Russia and Iran — becoming an important energy hub serving the needs of the European Union (EU). 

The so-called hostage diplomacy of the Islamic Republic of Iran refers to a political and diplomatic strategy in which Tehran uses the detention of Western nationals, dual citizens, or Iranian citizens residing in Europe, Australia, or the United States as leverage in diplomatic negotiations. This practice aims to exert pressure to secure political, economic, or diplomatic concessions as part of Tehran’s asymmetric response strategy. Hostage diplomacy remains a controversial yet effective tool from the perspective of the Islamic Republic of Iran, given its context of economic sanctions and diplomatic isolation.

Relations between the United States and the Islamic Republic are marked by history. On the Iranian side, the overthrow of Prime Minister Mohammad Mossadegh in 1953 weighs heavily on the perception of the United States. On the American side, the events linked to the 1979 Islamic Revolution remain a trauma after more than forty years. The agreement on the Iranian nuclear program, known as the Joint Comprehensive Plan of Action (JCPOA) and signed in July 2015, was therefore a momentous first step towards a possible reconciliation. Unfortunately, the process was interrupted by the United States’ withdrawal from the agreement and the implementation of a "maximum pressure" policy by the Trump administration in 2018.
