Most liberals and proponents of hegemonic stability theory, along with America's extraordinary military power, have created international institutions, organizations, and regimes, produced public security, financial, commercial, and economic goods, multilateralism, and avoided unilateralism.

But with the coming to power of Donald Trump, and the policy of "America First" and the withdrawal of many international institutions and regimes, the refusal to produce public security and economic goods and the end of what he calls "free riding", the pursuit of nationalism Economic, one-sided, and ultimately disregard for the interests of other actors, including friends of allies, have seriously challenged America's position of "liberal hegemony.” Therefore, according to the teachings of the theory of hegemonic stability, the main purpose of this study is to state: US foreign policy in the Trump era, while passing the declared slogans, has undergone serious changes compared to the past, These changes have put the country's position in jeopardy, as Trump has taken steps to undermine the position of liberal hegemony by going through the elements of legitimacy.
