Modeling the Factors Affecting the Nuclear Negotiations of Iran in 5+1 with the Fuzzy Approach: Structural Equations

The nuclear deal between Iran and the P5+1 countries in Vienna on July 14, 2015, is considered a historic day in the history of international relations. The success of the nuclear negotiations between Tehran and the P5+1 countries is an example of the importance and persistence of international politics and diplomacy and will be the basis of stability in the region, and this agreement can be described as a victory for diplomacy. Considering these issues, the purpose of this research is to model the factors affecting Iran's nuclear negotiations in P 5+1.

This study is in the field of descriptive-survey research of the correlational type and according to the purpose and topic of the research, it is practical and cross-sectional in terms of time. This research has been determined by the use of snowball sampling among experts in the field of nuclear negotiations in 2021. Moreover, based on the type two fuzzy method and partial least squares method of the research model, the following results were obtained; individual resources 0.441, role resources 0.485, government variables 0.76, social changes 0.593, international variables 0.573, the internal environment variable 0.582, informal influential groups 0.834 and unilateral and multilateral sanctions as much as 0.149, influenced nuclear negotiations.
