What is the Process of the Return of US Sanctions Against Iran?

Following the announcement of the US withdrawal from the nuclear agreement and the issuance of Donald Trump's directive to reinstate nuclear sanctions, the European Union is now facing the challenge of maintaining the current conditions. The US Treasury Department has announced that sanctions related to Iran's nuclear program, which were extended until May 11, will be reimposed in the next three to six months. US officials, including Donald Trump, have stated that new sanctions will also be added to the suspended sanctions. On the other hand, the European Union, on Wednesday, May 8, emphasized its commitment to the nuclear agreement, promising Iran that as long as the Islamic Republic adheres to its commitments, the EU will prevent the return of European nuclear sanctions. However, in recent months, the main question has been how and to what extent the European Union can prevent the expansion of US sanctions against Tehran following the US exit from the JCPOA, and whether it has any desire to do so. We asked Mehrdad Emadi, an economist and expert on economic and financial sanctions in London, about this question and the process of the US sanctions against the Islamic Republic.
