The dynamics of changes in United States (US) foreign policy in the new era show increasing complexity and challenges. In recent years, the US has faced various shifts in its diplomatic outlook and approach. One of the main factors influencing this change is the rise of new global powers, such as China and Russia, which have changed the world’s geopolitical landscape. This dynamic can be seen through a shift from a unilateralist approach to multilateralism. In previous eras, the US government tended to make decisions unilaterally. Today, however, there is a greater emphasis on international collaboration, especially on issues of security, climate change and trade. The Paris Agreement and partnerships in global health initiatives demonstrate the US initiative to cooperate on an international scale. US foreign policy is also increasingly influenced by domestic issues, including civil society movements and pressure from voters. With increasing public awareness of global issues, the government in the US is starting to respond with policies that are more in line with the aspirations of the people. Social activism and the use of social media have become important tools in shaping narratives and driving foreign policy change. A change in strategy is also evident in commitment to traditional allies. Alliances such as NATO and partnerships in the Asia Pacific are strengthening, while relations with authoritarian states are increasingly being challenged. For example, a more assertive approach to human rights violations in countries such as China and Russia reflects a shift in the values espoused in foreign policy. In an economic context, the US has paid more attention to the issue of sustainable and fair trade. Focus on supply chains and collaboration in the field of technology are also a major concern, to ensure competitive advantage in the global market. Free trade must now take into account social and environmental dimensions, making foreign policy more inclusive. Digital technology also influences foreign policy. Cyber threats and disinformation are a major concern in maintaining international stability. The new policy includes measures to counter cyber attacks as well as to educate the public about the importance of media literacy. This shows that security does not only revolve around military power, but also on protecting information. Public diplomacy strategies are also undergoing transformation. In the digital era, engagement with the global community through online platforms is important. The US government uses social media and digital campaigns to convey foreign policy messages, ensuring that they can reach a wider and more diverse audience. Furthermore, another challenge facing the US is the refugee and migration crisis. Handling this issue is not only a humanitarian problem, but also affects political stability at home and abroad. This calls for adjustments in foreign policy to create a more humane and effective approach, which can reduce social tensions and support refugee rights. Environmental priorities and climate change weigh heavily in US foreign policy. Cooperation to reduce carbon emissions and support sustainable development is an integral part of recent diplomatic strategies. By assisting developing countries in the transition to clean energy, the US seeks to strengthen its position as a global leader on environmental issues. These changes reflect a cultural transition in US foreign policy. Community involvement, emphasis on human rights values, and social responsibility are important pillars. In this case, foreign policy changes are not simply a response to global challenges, but also a reflection of the moral and ethical development of US society.
