The importance of coherent foreign policy is due to the foreign policy's impact on countries' survival, development, stability, and security. Different individuals, institutions, organizations have different roles in foreign policy under any conditions in different political systems. This article presumes that foreign policy is the continuation of internal and domestic policy. The present study aims to explain foreign policy by highlighting different and diverse decisions and policies. This article includes a conceptual framework, a section that will explain realistic and idealistic policy, mental foundations of utopian and real policy-making in the Islamic Republic of Iran, an explanation of the foreign policy, and finally the conclusions. The main question is: what effect had a plurality of ideas and multiple structures on Iran's foreign policy in the period (۲۰۱۳-۲۰۲۱)? The hypothesis of the research using analytical and explanatory methodology is: During the period (۲۰۱۳-۲۰۲۱), the plurality of ideas and multiple structures as a roadmap has played an important role in the coherence and orientation of Iran's foreign policy.
