Political geography is the study of the political dimension of space, and one of the most important elements of this dimension is security in general and national security in particular. The essential position of the security of countries is evident in the national strategies of governments. For this purpose, it should be able to provide a comprehensive functional guide for the policy makers and security managers of the countries, using a structured system in which the relationships are standardized. Therefore, the establishment of the doctrine of national security requires the design of a suitable model to evaluate the degree of realization and its developments. The aim of the research is to develop a comprehensive theoretical model of national security policy. The research carried out on the background of the subject has not yet produced a comprehensive model for assessing national security, so the main focus of the research is on designing a comprehensive theoretical model or mechanism for national security policy-making based on effective factors and discovering the relationship between these factors. The desired model will explain the emergence of national security with the main features of the political geography approach
