The term geopolitics, having seen many ups and downs, is used by politicians in international literature and discourse for a little over a century to reflect views in the field of international relations. In Iran, after the rise of Islamic Revolution, the slogan “neither East nor West” signified the adoption of an independent defense policy by the founder of the Revolution (RA) which was rooted in the divine goals of Islamic school; therefore, thinkers of military strategies were inspired to more deeply consider geopolitics and its sub-disciplines in order to develop the national defense policies. In the same vein, the purpose of this study is to delve into “the impact of geopolitical factors in Pakistan on Iran’s defense policies (a case study of military factors) in the type of an applied research and a descriptive-analytical one in terms of method. The population of this study is 60 people and the outcome indicates that “defense policies, security and development of military capabilities; military power and quantitative and qualitative capability of the armed forces; military facilities and industries and contracts and defense agreements forged by Pakistan” have affected Iran’s defense policies

The main purpose of this review article is to review and compare how Iran's and Pakistan's energy systems will be transferred to a 100% renewable energy system by 2050. Iran and Pakistan are neighbors and the main source of energy in both countries is fossil fuels. But, Iran has major fossil resources, while Pakistan is an importer of fossil fuels. Therefore, in this article, by reviewing the literature on designing a 100% renewable energy model for Iran and Pakistan, has been attempted to compare the energy transfer paths in these two countries. To simulate a fully sustainable energy system, an approximate hour-by-hour model for both Iran and Pakistan has been used between 2015 and 2050, which includes demand for electricity, seawater desalination and non-energetic industrial gas sectors. The levelised cost of electricity estimating show that renewable resources have the best efficiency and lowest cost among all options for achieving an energy system with a zero-emission of greenhouse gas. The analysis demonstrates that it is possible to carry out this transition from a technical and economic perspective with some measures being vital for achieving this ambition in a cost-e ective manner.
