Conceptual models are representations of a system that easily show us the abstract concepts of the relationships between objects in the system. In fact, no matter how systematic and meaningful the drawing of models in the field of science, can improve the understanding of issues and topics. Meanwhile, the region of Southwest Asia is of special geopolitical importance due to its privileged geographical facilities and locations, as well as its rich resources. But the developments in this region have caused the involvement of various actors. These actors, with different and even contradictory goals, ideologies, and behaviors, have caused the crisis in the region to continue. In other words, no matter how much the geographical source of power is geopolitically appropriate if there is a basis for more attractiveness to log in and the role of actors too large and large. If you are currently presenting a new tariff on geopolitics and dividing geopolitical actors into three groups: main and focal actors, semi-peripheral actors, and peripheral actors, in the next step you have tried to systematically present the geopolitical relations of Southwest Asia by presenting a conceptual model. Because accurate knowledge of the geopolitical relations between these actors allows geopoliticians to formulate the best strategy for the volatile region of Southwest Asia.

The boundaries are completely complex spatial-geographical phenomena that include several dimensions and parameters. This spatial-geographic phenomena has become the focus of governments due to their importance and position in order to establish order and security within the country and to protect national interests and different efforts are done to protect them. To achieve this, the first and basic step is to know the dimensions and parameters that form and affect the borders. This research tries to determine these dimensions and parameters and their impact on urban development of Javanrood city. Accordingly, a questionnaire consisting of parameters and components affecting the development of border areas based on nine dimensions (territorial, socio-cultural, economic, political-governance, geopolitical, defense-security, historical, legal-structural and technological) is projected. The present study is descriptive- analytic in terms of it's practical purpose and in terms of the method of data collection. Since the aim of this study is to investigate the effects of security parameters on the development of border cities, the research is a descriptive correlational study. The results showed that among the components of the territorial dimension, environmental resilience; among the components of the socio-cultural dimension, the existence or absence of social capital in the border city; among the components of the economic dimension, the dependence of border residents on economic interaction with border; among the components of political dimension, level of freedom of action of local governments on both sides of border; among geopolitical components, geoeconomic position of border; among the defense-security components, intervention of local players; among the historical components, human and physical commonality between the two sides of the border; among the components of the legal and structural dimension, the government's attitude towards the people and the border; and among the components of technology, border infrastructure and technologies are as the most important and influential factors influencing the border development of Javanrood city.

Introduction
Developments in recent decades have caused wars to undergo extensive transformations and changes in terms of nature, corresponding to this change of governments, in order to face these developments and changes, it is necessary to change one's outlook and perception in designing strategy so, they can move in harmony with the evolution of the nature of wars and reduce the challenges and damages caused by it on their territory as much as possible. In the meantime for prevention of the strategy of defense of the territory according to the new nature of wars, it can have a prominent position. Because the land defense plan as one of the land plan approaches is trying to rationally organize the land according to its capacities and potentials with an emphasis on defense and security. In a way that can maintain the security and integrity of the land, guarantee the independence and protection of the people against any attack and threat of the enemy, insecurity, create gaps and faults, wise and appropriate distribution of vital places and sensitive centers and infrastructures, balanced distribution of defense forces- It provided security in the territory on according to the capacities and facilities of the territory. Based on this, the present research seeks to extract the effective components on the design of the defense strategy of the Middle East countries, so that based on it, they can reduce the insecurity and costs (financial and life) to the extent while maintaining their survival to reduce the space of the country.
Research methodology
The current research method is based on content analysis and library and field sources (interview) were used to collect information. In the library findings section, components have been extracted from past theories and works, and in the second step, the components have been confirmed by interviewing seven of the scientific-military elites and reaching theoretical saturation.
Results and discussion
The studies conducted to extract the components affecting the defense of the Middle East countries show the absence of a comprehensive scientific theory and work in this field, and various theories and works have been used to extract the components. In this context, 12 theories and eight experiences of defense training of different countries have been examined and analyzed, and based on them, 130 components have been extracted and provided to experts and thinkers in this field. The field of theoretical saturation has been extracted with seven scientific-military elites. The results of the examination of the theories and approaches that have been collected in the field of topics related to the defense of the land, along with the interviews that have been conducted with related experts and thinkers, show that both parts are Various factors on the diversity and extent of 130 components have been effective in designing the defense strategy of the Middle East countries, which are given in the form of 15 dimensions in the form of the following table based on importance:

Conclusion
The results of the investigations carried out in this research show that the defense based on the transformations and developments that have taken place in different fields has undergone extensive changes and necessarily the governments in order to be able to face this changes that have taken place in the field of threats and technologies, etc., to update and make their defense strategies efficient, they should be able to take a comprehensive and up-to-date approach to the defense of the land. According to the findings of the present research, it shows that land defense as one of the forward strategies of the governments in an up-to-date and comprehensive manner includes 15 dimensions and 130 components that should be used in the design of the strategy should be considered.
