Investigating the Impacts of Iran, Saudi Arabia, and the United States on Regional Equilibrium Patterns of Regional Power in the West Asian Geostrategic Zone after 11TH of September.

The events of September 11, led to formation of, new regional power balance in West Asia, that regional goals of its actors ranged from balance of power to balance of threat. In order to explain function of balance of power approach; By examining regional goals of the actors of West Asian theorists, he dissected balance of power in the next decade. The balance of traditional power is predicted. As a result of the findings, outlook for the future is that probability of Iran's convergence with Saudi Arabia and the United States is low (the average intensity of regional convergence is 41.8%) and in the region, balance of traditional forces is still the most likely option. The level of tension created by the actors' goals belongs to Saudi Arabia, Iran and United States, respectively. Saudi Arabia is very influential from the United States and has a supporting role in US regional policy, and Iran has a deterrent role. This study is theoretically and practically important. The data were collected by library method (shooting tool), then the interrelationships between the targets and the actors were analyzed by the "future" research tool "Maktor", "Grapher" geometric design software, game theory and "diagonal matrix" pattern.
