| Since the end of the cold war,the United States has been the dominant player in the Middle East.However,with the impact of two wars on terrorism and the outbreak of the "Arab spring",the regional order in the Middle East,which was dominated by the United States,was gradually broken,and the whole Middle East gradually presented a fragmented geographical situation and its chaotic security situation.The United States is gradually adjusting its global strategy due to its limited national strength and the treacherous international situation,keeping a certain distance from the Middle East affairs and avoiding deep involvement,and returning to the role of an offshore balancer to some extent.The "light footprint" in the Middle East strategy of both the Obama administration and the trump administration is clear.The rise of Iran is the biggest change in the Middle East’s geopolitical landscape as Washington loses its grip on the region.Iran not only maintained relative social and economic stability during the upheaval in the Middle East,but also reached a strategic compromise with the west by seizing the important opportunity of the strategic contraction of the Obama administration.The signing of the Iran nuclear agreement liberated Iran from the common pressure of the international community and gradually realized the rise of shi ’ite power in the Middle East.Iran’s growing power poses a serious threat to the interests of the United States and its regional Allies,and more urgently,Iran’s growing nuclear and islamic ambitions pose a huge challenge to the strategic balance of the Middle East and Washington’s traditional interests in the region.The trump administration’s strategy in the Middle East and its policy toward Iran have been set against the backdrop of global adjustments in the United States.With the global politics,the economic center of gravity is tilting towards Asia and the Pacific.The United States from the Obama administration started the strategic center of gravity to the east,so the government’s policy toward Iran trump is also based on the strategic thinking,the current strategy of American global strategy is characterized by contraction,in the Middle East direction on the regional situation facing the increasingly serious,complex geographical environment,difficult to eradicate the terrorist forces,hostile geopolitical challenge,the international energy security threat is government’s Middle East policy factors trump,doesn’t mean Washington but strategic contraction decreased the degree of attention to the Middle East.Faced with the growing geopolitical influence of Iran and the growing power of shia in the Muslim world,the trump administration did not adopt the "engagement policy" with Iran under the "light footprint" strategy of its predecessor Obama administration,but instead adopted a tough "containment policy" with Iran.There are multiple factors behind the trump administration’s Iran policy.Ten months after taking office,the trump administration has unveiled a "new strategy" for Iran.Increased sanctions against Iran,particularly on the economic front;Give priority to the fight against and containment of Iran’s islamic revolutionary guard corps;Do everything possible to prevent Iran from acquiring and developing nuclear weapons.Overall,the trump administration’s Iran policy reflects its unique strategic considerations,which include both the fundamental goal of containing Iran and uniting Allies,and stabilizing petrodollars to serve the deeper goals of its global strategy.This paper will analyze the reasons,objectives,characteristics and prospects of the trump administration’s Iran policy through four chapters.Specifically,the first chapter mainly analyzes the reasons for the trump administration’s Iran policy at the beginning of its coming into power.The second chapter mainly studies the objective value position pursued by the trump administration’s Iran policy,which is multi-layered.The third chapter mainly summarizes the characteristics of the Iran policy of the trump administration.The fourth chapter mainly focuses on the policy practice evaluation and prospect analysis of Iran since the trump administration came into power.Strategic game between America and Iran is the main contradiction in the current Middle East situation,in the face of the Middle East geopolitical pattern of continuous differentiation and recombination,trump government after taking power no matter what strategy in the hot issues in the Middle East,the Middle East policy at the heart of the concern is will always contain and hit Iran,avoid by its power in the Middle East,and to achieve the strength relative balance,reduce tensions in the Middle East,a new regional order,realize the maximization of the interests of Washington in theregion.Under such circumstances,Iran has become an important and major obstacle for the United States to restore order and stabilize its interests in the Middle East.The strategic game between America and Iran will continue for the foreseeable future,and will become more acute and unpredictable.Under the President’s campaign slogan of "make America great again," Washington is trying to reshape a us-led regional order in the Middle East.From trump government for more than three years practice of the policy on Iran,the Iranian policy can make us get some practical benefits in the short term,but in the long run trump’s Iran policy will make the loss of strategic flexibility,harm the interest of the United States in the Middle East,even for the hegemony of the United States a foundation caused immeasurable influence. |
