In this chapter, the military situation refers to expressing the military importance of the Persian Gulf region and its strategic nature by examining the military bases of foreign powers in the region; the direct presence of the fleets of major countries in the Persian Gulf; the bulk purchase of weapons by the countries of the Persian Gulf region; and the military force of the neighboring countries of the Persian Gulf. Benefiting from a series of special natural and political features, the Persian Gulf is significant in military defensive and offensive strategies. Using this feature, the Persian Gulf and the Sea of Oman connect to other lands and seas. As with the benefit of this special feature, it is connected to the Indian Ocean, the Pacific Ocean, the Atlantic Ocean, the Red Sea, the Mediterranean Sea, and the Black Sea. As a result of geographical compatibility and legal issues, the Persian Gulf and the Strait of Hormuz have created an outstanding position for the passage of special naval and air force units. Its depth and width are such that nuclear submarines and aircraft carriers can pass through it. This position, which existed since ancient times, was emphasized by world geopolitical thinkers during the nineteenth and twentieth centuries. Accordingly, the super-strategic position of this region will be maintained while influencing other regional and trans-regional developments.
