Ethnic divergence and investigation of its identity, spatial and political aspects is one of the central topics of geopolitical studies. Although different disciplines have addressed the fundamental applications of this cultural-geographical phenomenon, the ambiguities about the position of ethnic studies in geopolitics sometimes results in blurred expression of its epistemological domain with other scientific domains such as sociology, political science and international relations. In this regard, the aim of this paper is to present a framework and theoretical model for study of ethnic divergence in geopolitics. This is a descriptive-analytical study. The data were collected by library study. Results of this study show that if the ethno-nationalism is based on two bases i.e. bedrock (spatial-politics) and mechanisms, geopolitics will investigate the domain mainly focused on environmental elements (spatial-politics). This means that national, regional and global environments are the platforms that facilitate ethnic divergence. Therefore, it can be said that geopolitics addresses effective environmental bedrock contributing to formation of ethnic divergence which can play an important role in the emergence of and guiding of divergence mechanisms. <br /> 

Due to geographic importance, India, China and European states are the largest potential natural gas markets of Iran. Iran natural gas and gas condensate production reached to 6.5 million barrels until February 2019. This gas will be received by Europe, finally. Europe depends on gas import from Russia, a matter that concerns gas importing states. Europe security strategy is focused on decrease in the level of dependence on Russia which is emphasized by Europe security perspectives. The research is intended to investigate these issues: what is Europe strategy to provide its energy security? And how do Iran’s gas resources affect Iran and Europe relations? The research hypothesis is that Europe is intended to develop its relation with Iran in order to decrease in Europe energy dependence on Russia. The research is based on descriptive-analytic method and also it is applied in terms of its goal. The research results show that Iran is the only state that can end Russia dominance on Europe energy supply, and European states can reconsider Iran’s role to promote Europe energy security and to decrease in the EU dependence on Russia.

The Middle East region has been a longstanding major source of concern for American leaders due to its eternal religious and cultural relevance, a strategically pivotal location, huge oil reserves, interlocked and intractable conflicts, and the persistence of major security threats such as terrorism and the risk of nuclear proliferation. <br />The Middle East region is undergoing security shifts. Regional security in the Middle East will be changed in Trump era. Security and power in each region has connected, empowered and influenced a new generation of young people, who are questioning political authority with new intensity. <br />The outcomes of the Arab Spring mostly disappointed the world and its policymakers. The region is violent; disfigured by inter and intrastate conflict and by sectarian divisions. Power and security in Middle East countries has been fragmented. The nature of security in Middle East policy is based on Proxy war and Non-state actor’s initiation. Non-state actor who are active in the region, are both a symptom of state weakness and amplify the threats to states. <br /> The Middle East region recognize with economic bedrock of the regional security as exports of hydrocarbons is under threat. Surveying the region shows that, in the throes of historic turmoil and facing massive challenges. The US, UK and other European countries has critical interests in the region, both economic and security. Moreover, what is happening in the Middle East, it will be expanded to other regions and does not stay in the Middle East. In this situation, Trump’s policy and strategy lead to instability, turmoil and power transition. For control and leading this process, world politics to need co-operational security model with other great powers and regional actors like Iran, Turkey and Saudi Arabia. <br />This article, by descriptive-analytical method, seeks to study the "Trump’s Grand strategy in the Middle East". the main hypothesis emphasis that “U.S strategy on Middle East in Donald Trump policy based on offshore balancing, proxy war and increasing chaos’’. <br />  <br /> 

One of the issues discussed in geopolitics is the role of international straits (canals); as such, it is of great importance to investigate their geopolitical and strategic role. It is because the straits are the places of distribution of power, where the competition of governments is very evident in using the potential of geographic space to achieve greater benefits and ultimately to gain power in international relations. Even in some cases, countries not located around the straits enter many ways in order not to lag behind other countries. That is to say, there is a kind of conflict and competition between countries over the use of straits, especially the countries bordering the strait. Therefore, the strategic straits play a decisive role in the power of nations and their fate and also in the foreign policy of the coastal states along with the balance of regional and global power, as a result, their study is essential for political geographers and geopoliticians. One of the most important straits in the world is the Malacca Strait whose investigation strategically and geographically provides important points. Using descriptive-analytical method and also based on statistics and figures for plotting diagrams in this paper, it has been tried to study the role, geopolitical features, and importance of Malacca Strait for coastal states and conditions as well as factors causing challenges and crises for the strategic role of the strait. According to the results, as one of the major international straits, the Malacca Strait has strategic potentials in the regional and global arena and coastal governments need to rely on targeted and strategic plans to combat the challenging processes in this strait<strong>.</strong>
