Since the American military proceeding against Iraq in 19 March 2003 and the collapse of Saddam Husayn's Government, the Iraqi Shi'as undertook the main power in political-security events of the country. This event along with the 33 days fighting of Hizb ul-llah and Israel (2006), which caused Hizb ul-llah to change to an important and influential player in the region, resulted in strength of Iran's role and influence in the developments of Middle East region as an important security-regional subsystem. This process brings about the Sunni conservative political-security elite to state worriment about the increase of Shi'a power and influence, especially Iran, and the emergence of an influential 'Shi'i Crescent' in the region. But it seems that there are latent pu rposes and policies behind the threat of 'Shi'i Crescent'.

After the collapse of the Soviet Union and the Eastern Bloc, the series of actions of the United States in the expansion of NATO in the peripheral regions of Russia caused Russia's political and military provocation and the formation of this country's aggressive policy in the Eurasian region, such as the crisis in Ukraine. many believe that this invasion has also dealt a heavy blow to Russia due to the financial sanctions and logistical support of the European Union and the United States. An event that can lead to a serious conflict between Russia and the United States and the war in Ukraine will be worn out. The current research is trying to answer the question of what effect did Russia's war against Ukraine have on American Hegemony? The proposed hypothesis is that the war between Russia and Ukraine in 2022, due to the conflict of interests of Russia with the United States and its allies, especially geopolitical dominance over Ukraine, will become an arena for the decline of the American liberal Hegemony. The aim of the upcoming research is to investigate the effect of Russia's war against Ukraine on the American liberal Hegemony from the perspective of hegemonic stability theory. The research method is also an explanatory method that focuses on finding cause and effect relationships between the research variables to understand the conflict between Russia and Ukraine and its impact on the Hegemony of the United States.

After the collapse of the U.S.S.R, NATO not only didn’t collapse but extended in it’s mission and geography. This article through the survey of theorize and approaches which have tried to describe this phenomena, is analyzing the role of American Hegemony, NATO as a valuable asset for the U.S, has a considerable role in the consolidation of American Hegemony, and continuity of American influence in Europe. It gives America necessary means to impact on the regional and World events and Trends. The U.S has tried to strength this transatlantic organization and through which it prevents the rise of similar, but independent organizations in the Europe. Accordingly NATO has found further role in the security environment of West Europe, Est Europe and other neiboring regions and is becoming effective in the consolidation of American Hegemony.

With the collapse of the Soviet Union and the end of the bipolar system, the America claimed the position of undisputed power and the most powerful government in the international system and turned into an actor that has the ability to guide international rules and procedures alone. However, by challenging America, other great powers continued their efforts to change these conditions with long-term and strategic plans. China is one of these great powers that has the potential to become a superpower, and occupying the current position of the United States has worried American strategists and officials. With the outbreak of the Corona crisis in 2019, many hypotheses were raised regarding the fakeness of this virus to curb the economic power of China on the part of the United States or, on the contrary, on the part of China to counter the unilateralism of the United States in the international system. Assuming this competition between China and the United States of America, this article tries to answer this question did the corona virus spread globally in line with China's balancing approach against the hegemonic power of the United States or, on the contrary, the containment of China by the United States? At the end, the article evaluates the hypothesis that the behavior of the central powers of the international system is influenced by the structure of the international system and the nature of the competition between the central actors of the international system has changed, hence we are witnessing scientific-technological competitions.

Throughout history, the rise and fall of great powers has always been one of the most important and fundamental issues in the international system. With the beginning of the 21st century, observers and analysts have argued that the transition period in the international system has begun, and although the new era does not have a clear formulation, what is clear is that America's hegemonic position has weakened. So the question is, what is the reason for the decline of American Hegemony based on Robert Cox's theory? In answer to this question, it is hypothesized that the decline of American Hegemony has been due more to the inappropriate behavior of the United States in recent decades than to the balance of power of the world powers that It has focused more on hegemonic political behavior than on trying to create satisfaction based on Robert Cox's theory of Hegemony. Research findings using descriptive-explanatory research method show,American political behavior is different from Robert Cox's view of Hegemony and domination has played a greater role in American performance than consent and this has affected the decline of that country's Hegemony.

The military rise of China is one of the important events of modern history. It is for more than two decades that China by taking up rational policies in domestic and international arena has achieved tremendous progress. These accomplishments along with vast potential of this country has changed it into a great and influencing power and one of the candidates of superpower position in the twenty first century. Since the United States considers itself as the only superpower of the modern world, the rise of China is a Challenge to its Hegemony. This Challenge points out the necessity of responding to it. The present article while evaluates the Chinese military progress, its impact and consequences raises this question that what should be the United States policy for facing the rising military power of China? The paper also evaluates the hypothesis that the military development and growth of China is the indication and its tendency for world Hegemony and becoming a superpower in international arena. Thus with the rise of China and its establishment as a world power in new world order in the coming decade, major contradiction will increasingly emerge between the United States and China. This conflict of interests, besides ideological difference, will lead to the strategic interest rivalry in Asia-Pacific and even in the whole world. Since these developments do not conform to the long range policies of the United States it will pursue a two pronged strategy of containment and participation to face this security dilemma.

A review of the turbulent hegemonic competition between Iran and the United States in the past 40 years shows a conflict-filled process with long ups and downs, in which the two countries have always taken the path of conflict and confrontation with all the tools and capacities of their domestic and international power. In this framework, the formation of the current of resistance and the stabilization and strengthening of its hardware and software power components under the shadow of authentic Islamic principles, including the negation of the mustache, was able to sideline the strategic goals of the regional aggressors, from America and Israel to their Western and Arab allies. The research method has a descriptive and analytical nature. This article is based on the teachings of the theory of "hegemonic stability" realism and is based on the assumption that General Soleimani was able to design a model of hegemonic deterrence in West Asia while breaking the foundations of the American hegemonic system in the shadow of structuring and organizing the resistance movement. We have gathered part of the information required for this research by analyzing the content of American national security documents in the years 2002 to 2021 and part by using media news reports and library sources. The results of this research show that Sardar Soleimani's initiative, both during his worldly life and after his martyrdom, was able to combine the rivalry between Iran and America in West Asia with the relative victory of the resistance axis and the hegemonic stabilization of the resistance discourse in this region. The analysis of terrorist incidents after the US attack on Iraq shows that instead of reducing terrorist acts, this attack caused the spread and strengthening of terrorism in West Asia, and this situation faced the national security of the Islamic Republic of Iran with a new Challenge. In fact, the American attack on Iraq gave the opportunity to the militia groups to develop their base in this country and recruit troops under the pretext of fighting against the United States with the goal of holy jihad. On the other hand, the critical situation in Iraq caused by the collapse of Saddam Hussein's regime and the power vacuum in this country made it easier for these groups to recruit members and get armed. Meanwhile, by dominating Iraq and using strategies to establish hegemonic stability, America tried to use the opportunity of increasing terrorist activities in this country as a new lever against stability in the Islamic Republic of Iran. In this situation, the command of the Quds Force of the Islamic Republic of Iran, by designing smart strategies, not only tried to curb the growing trend of Takfiri forces in Iraq but also managed to significantly prevent the increase of influence of America and its allies in Iraq.  In this article, using the teachings of the theory of hegemonic stability, we are looking for an answer to the question, how did martyr Soleimani affect the position of the axis of resistance and the hegemonic equations of America in the regional balance of power in West Asia? In response to this question, based on the teachings of the theory of hegemonic stability, we test the hypothesis that General Soleimani was able to design a model of hegemonic deterrence for Iran in West Asia while breaking the foundation of the American hegemonic system in the shadow of structuring and organizing the resistance movement. We have formulated this research using the method of post-event analysis and content analysis. Based on this, in this research, emphasizing the activism of martyr Qassem Soleimani, we show how the influence of structuring and organization leads to hegemonic deterrence of the axis of resistance. We have collected part of the information required for this research from the content analysis of American national security documents in the years 2002 to 2021 and part of it using media news reports and library sources. After a review of the theory of hegemonic stability and then a review of the US national security documents, we show the position of General Soleimani on the change of the US equations in West Asia.The conditions that arose in Iraq after the US attack show that the alleged US war against terrorism to change the existing situation in the region in favor of the US was not only unsuccessful but also provided the ground for the formation of new terrorist groups and strengthened terrorist ideas. The Iraq war also showed how the behavior and policies of the United States with the aim of establishing hegemonic stability in Iraq caused the terrorist groups that were present in this country before the American attack on Iraq, while multiplying into new groups, to continue their life in Iraq and the past actions Pursue yourself with more territory and wider goals.  By examining the American national security documents, we can reach the point that each of the American strategies, whether it is to deal with the proliferation of weapons of mass destruction, fight against rogue countries, or promote democracy and human rights, were linked to the issue of fighting terrorism and linking all policies to one issue. The fight against terrorism in order to achieve the hegemonic order can be clearly seen in the American national security documents. Despite this, neither the use of the aggressive policies of the Bush administration, Obama's approach, nor Trump's approach in the Middle East, which are all evaluated against peace and security, did not come to fruition due to what was reviewed in this article as efforts to change the status quo, and the continuation of America's presence in Iraq had no achievement except more insecurity and instability in Iraq and the region.It seems that the activities of the Quds Force of the Islamic Republic of Iran under the command of General Soleimani have been one of the components of deterrence, the dismantling of hegemonic stability, and the change of the American military equation in West Asia. To put it better, the Quds Force of the Islamic Republic of Iran was able to turn this area into one of the most unsafe areas for terrorists, including American soldiers and Takfiri terrorists, with the initiative of its commander. On the other hand, putting an end to the unipolar world hegemonic order will create deterrence in West Asia.  The most important initiatives of Martyr Soleimani in deterring and creating the destruction of the American hegemonic order and stability can be listed in cases such as strengthening the deterrence of the axis of resistance in the shadow of new developments, evading American sanctions, removing the platform for the reprocessing of terrorist groups in the region, strengthening military infrastructure and expanding the domains of the axis of resistance. Of course, it should be noted that Iran's competition with the United States and its allies for Hegemony in the West Asian region continues, and the United States, within the framework of the strategy of distant balance and aggressive realism that we mentioned in the theoretical part of this research, continues to build its network to deal with the axis of resistance continues. It is worth noting that in spite of the huge damages caused to the member countries of the Islamic Republic of Iran's Quds Force as a result of the absence of General Rashid, the network and systematization of the resistance axis, which is derived from the theories of this martyr, still has a great power to advance this path of dismantling the American order and Establishing Iran's hegemonic supremacy.
