One of the core issues in the complex international system is the order management of phenomena within particular realms of the system. This study, premised on the complex phenomena within the international system, strives to address how regional order management along with regional regulation are achieved within the complex international system. The findings of this study suggest that systemic interventions, which impact the key variables of a regional system and are initiated by trans-regional actors, and hegemonic and regional power, are proposed as a means to manage issues within complex regions. However, the degree of these interventions can vary significantly, depending on whether the regions are symmetrical or asymmetrical. In symmetrical regions, given the heightened sensitivity and vulnerability of the actors involved, as well as the robust regional bond and coalition structures, there exists a Nash equilibrium, which serves as the focal point for resolving regional conflicts. In asymmetrical regions, due to the fragile nature of the bond and coalition structures and the contentious regional issues, conflicts tend to escalate. Moreover, this often leads to maximum interventions by trans-regional actors.

The main purpose of this study is to investigate the symmetric and asymmetric causality relationship between three variables of global geopolitical risk index, crude oil price and Middle East region's defense expenditures during the years 1988-2021. For this purpose, the Granger causality test of Hatemi-J (2012) has been used in the form of bivariate analysis. The results of the symmetric causality test between the variables show that only the existence of a one-way causality relationship is confirmed from the side of crude oil price to the Middle East region's defense expenditures. The results of the asymmetric causality test also confirm the one-way causality relationship from the positive shocks of the global geopolitical risk index and the crude oil price to the positive shocks of Middle East region's defense expenditures. Also, the one-way asymmetric causality is confirmed from the side of negative crude oil price shocks to the negative shocks of Middle East region's defense expenditures and from the side of positive global geopolitical risk index shocks to positive crude oil price shocks. Based on this, it can be said that an increase in the global geopolitical risk leads to an increase in the crude oil price. The increase in the global geopolitical risk and the crude oil price also leads to an increase in defense spending in the Middle East region. Also, it can be expected that with the decrease in the crude oil price, the defense expenditures in the Middle East region will decrease.

They showed the system of the Iran to be inefficient in the international arena, and although they imposed a heavy cost on the nation and the government of Iran, they did nothing with the vigilance of the officials and the perseverance of the people. After the end of the war, the military and national officials thought of strengthening the deterrence power in the country, because according to the military and defense capabilities created in the war, the unique combination of the Iranian armed forces, national spirit, experience of sacred defense, made Iran a regional power. and a kind of deterrence was created in the country. Deterrence is a strategy in which a power uses the threat of retaliation to prevent an enemy attack. The idea of ​​deterrence has a long history, some believe it is as old as war itself.Deterrence does not mean that you necessarily use weapons; Rather, one of the important dimensions of deterrence is its managerial and psychological aspect. As much as Iran's capabilities are analyzed in the world, it leaves its effects in the international system, but this is not enough. Because the of Iran needs deterrence at a high level to advance the goals and ideals of the revolution, and it must have both types of deterrence, i.e. symmetric and asymmetric, according to regional and extra-regional threats and manage them. This research is applied and its method is descriptive and analytical, and its purpose is to address the need to improve Iran's defense deterrence power.
