Security, as one of the main duties of governments, requires policy-making in this area. In this regard, modeling is one of the techniques to facilitate the understanding and implementation of the policy process which help the authorities . This article aims to design a desirable policy model in the field of internal security in the Islamic Republic of Iran. The purpose of internal security is to create a satisfactory atmosphere of security feeling among the community, which results in a reduction of the gap between the demands of the people and what they have in hands . Given that people play a pivotal role in security issues, people satisfaction is considered as an important indicator for measuring its internal security. . Policy performing is next step , which Etzioni pyramid model (EVL) was designed to make and increase the satisfaction and then the internal security as the sufficient model . In this model, the implementation of domestic security policies is largely in line with the values and norms of the people, and there is little use of force, coercion and fear. In the meantime, a modest amount of remuneration is also considered. After policy implementation, it is time to evaluate the policy introduced by the Hirschman Triple Model (E.V.L). According to this model, implementation of policy has been a good thing if it would lead to loyal people or caused the protesters transformed to the loyal person . Otherwise, it would be undesirable to act if the people were opposed to the regime (exit option) or the protesters turned into opponents of the system. The evaluation results will lead to the adoption of one of the options for termination, modification (modification) or stop (major changes) in the policy

During the years of the last century, a new approach –the then academic discipline of public policy – prevailed the domain of problem-solving in various fields as a response to increasing public issues still needed to be addressed.
Among these fields, security issues emerged as a contextual framework in which states were serious about at a high level of attention and which resulted in a security agenda for the policy cycle.
As the policy cycle begins with the agenda setting phase and the departure point in this phase is defining the problem, we decided to clarify this point of departure in the present article using the security issues as a primary concern of the state authorities.

 Security, which is one of the main tasks of governments, necessitates the policy making in this field. In this regard, modeling is one of the techniques being utilized to facilitate the understanding and implementation of the security policy making which comes to help the statesmen. According to the definition of internal security, people play a pivotal role in security issues, and people's intrigue and satisfaction is an important indicator of internal security.

This study aims to design an optimum model in policy making of internal security of Islamic republic of Iran.

This is a qualitative research based on the analysis and description of the contents of some literature related to security events in the Islamic Republic of Iran. Data collection was carried out via literature review by means of reviewing written and unpublished sources and referring to libraries and electronic databases. A synthesis model from theories by Etzioi  (L.R.F) and Hirshman (E.V.Lwas designed and presented as an optimum model. In this model, the implementation of internal security policies is largely in line with the values ​​and norms of the people, and the use of force, coercion and fear is limited to a small extent, and a moderate level of remuneration is also considered. If the implementation of policies results in loyal people or makes protesters loyal to them (L.L and R.L), implementation would be optimum and it would lead to the end of policy. Otherwise, if the people are opposed to the system (exit option) or the protesters are turned into opponents of the system, implementation is undesirable and leads to the adoption of one of the correction options (minor variations including FL, LV and RV states), or discontinue (major changes including FV, LE, RE, and F.E) the policy.

External combination of two triangles allows policy makers to achieve different combinations compared to internal combinations which provides an optimum implementation of the policies; they can expect favorable and similar behavior because of such implementations.

After long consultations and negotiations for resolving Iran nuclear issue, both parts approved comprehensive negotiations joint action. After adopting the agreement, the basic significant issue is that the two sides agreed during the talks after what strategies, agreements and obligations be adopted and how and to what extent they are operational, and ultimately realize what the consequences come. On the basis of this assumption, we introduce game theory on the diplomacy after the agreement between Iran and the United States by adopting a strategy of mutual co-operation as the optimum design, the decision. According to the findings of this study, the nuclear diplomacy after an agreement between Iran and the United States, a dynamic game, complete with information and can positive-sum and the win-win game. Then play tree nuclear diplomacy after an agreement between Iran and US and plotted the options facing each and every one of them investigated and went on to find the answer to solving the outcome of the game and the way back into the fine profits as a result of Nash equilibrium and the game was the most logical, and the nicest strategy after the agreement sanctions and mutual commitment to its commitment to the agreement

In this research on this matter with the Iranian regime that endanger the change of the monarchy to the I.R Iran, friendly relations and strategic transformation and the US and Iran have a growing tension and the two to the military threats . The case study to question which nuclear challenge in relations between Iran and the United States with the use of how the game theory.went on the assumption that the proposed with regard to the game theory,nuclear challenge in US-Iranian relations with the sum of the game of positive,and can be solved.But evidence,and the findings of this study was to confirm the main hypotheses and came to the conclusion that the challenge of nuclear between Iran and the US with the government's policy on the eleventh a dynamic game,complete with information.then play tree nuclear tension between Iran and the US and plotted the options facing each and every one of them were investigated and went on to find the answer to solving the outcome of the game and the way back into the fine profits as a result of the Nash equilibrium;the suspension of enrichment from Iran and giving security guarantees from the US and lift sanctions.
