Analysis of the Continuation of the Presence of the Islamic Republic of Iran in Comprehensive Joint Action Program (BJAM) Based on Game Theory (2018-2021)

After the American withdrawal from the Comprehensive Joint Action Program (BJAM) and the non-fulfillment of the West's commitments, our statesmen adopted a new step-back strategy before the West agreed, in the case the West failed to fulfill its obligations. Against this backdrop, the United States and three European countries have threatened to take action against Iran's policy. The question that arises in public opinion is "What will be the end of this confrontation?" Possible options must be considered to answer this question. Iran's favorable choices, and America's and Europe's, especially the ones most likely to be. Although it is believed that the US and the West are eager to reinstate sanctions and new resolutions, this will not be the case if our country adopts clever measures and will be at a low level of efficiency. What is most sought after by the West and the United States is the diminishing fear of Iran's commitment to domestic and global public opinion, thus forcing Iran to stop in this new direction. In this study, the main question was asked which state is the best option for the Islamic Republic of Iran to continue its presence in BJAM using game theory? Based on the evidence, evidence, and findings of this study, we concluded that the continued presence of the Islamic Republic of Iran in BJAM is a dynamic game with complete and complete information. In this research, the game number tree of Iran's options was outlined and examined, and then, the answer and solve the game using the payback method, the result of which came to the option of taking decisive steps for reducing the obligations of the Islamic Republic of Iran.
