Abstract Given the fact that convergence and divergence in transatlantic relations and the role of Britain in the European Union have always been two important and determining factors in the EU's relationship with Iran, this article asks what implications Brexit and the presidency of Donald Trump in the United States could have for transatlantic relations and Iran. This paper assumes that Brexit and Trump's presidency—which have led to an unprecedented gap in transatlantic relations and security deficit in Europe—have promoted the EU to move toward reducing its strategic dependence and defend its own values and interests. Past experience has shown that such developments offer unique opportunities for the expansion of the Islamic Republic of Iran's relations with Europe, particularly considering the fact that Iran is one of the main bones of contention that have driven a wedge between governments on the two sides of the Atlantic Ocean.
