As is seen geopolitical motives are the main source of interest behind the active political, military and cultural activities of the Islamic Republic of Iran to expand its sphere of influence from the Middle East to the Caucasus, from Central Asia to Sub-Saharan Africa, from Latin America to the South East Asian Region. The billions of dollars of military resources that Iran has transferred, especially to Lebanon, Syria, Yemen and other regions assumed within its sphere of influence, show that costly foreign policy is a conscious choice for the Islamic Regime. In addition, it is clear that this costly foreign policy choice does not bring any significant benefit to the Islamic Regime in terms of political economy. It is known that inflation rates are over 40% and unemployment figures are more than 10% in Iran, which is in a serious economic bottleneck with the effect of economic embargoes along with its costly foreign policy choice. Also, it is seen that the Islamic Regime has not been able to use the extraordinary natural resources of the country efficiently and in a way that will provide welfare to society in general.
