The dynamics of international relations are greatly influenced by the election of the president of the United States, which is one of the superpowers. Every election, whether presidential or congressional, creates waves of change that influence foreign policy, strategic alliances, and global geopolitical dynamics. This election had a significant impact on other countries, especially in the context of diplomacy and economics. First, United States foreign policy often changes drastically depending on the elected president. For example, the shift from the multilateral approach used by the Obama administration to the ‘America First’ policy under Trump took many countries by surprise. This approach not only affects bilateral relations with allies such as Europe, but also raises tensions with countries such as China and Russia. Second, the presidential election also influences foreign investment flows. The uncertainty that arises during an election campaign may make foreign investors think twice before investing in America. If the elected candidate promises to increase regulations or change taxes, this will send a signal to investors about the stability of the investment climate in the US, which will then have an impact on the global economy. Third, the attitude taken by the new president towards international agreements can change the geopolitical map. For example, Trump’s decision to withdraw from the Paris Agreement has changed the dynamics of international cooperation on climate change issues. This creates an opening for other countries, such as the European Union, to take leadership on environmental issues. Alliances and strategic partnerships are also areas affected. During elections, campaign promises often reflect the candidate’s views on NATO and other multilateral organizations. If the new president is more likely to withdraw from alliances, this could change the balance of power in different regions of the world, triggering other countries to strengthen their positions or seek alternative alliances. Furthermore, presidential elections can also change immigration and international migration policies. Stricter policies in the US could lead to a large wave of migration, both from Latin America and conflict countries. This not only impacts U.S. demographics, but also the social and political stability of the immigrant’s home country. Overall, the impact of the United States presidential election on the dynamics of international relations is complex and varied. Changes in foreign policy, investment flows, international agreements, and immigration policies all play an important role in shaping the world order. This potential impact highlights the importance of the US presidential election, not just for the American people, but for the world as a whole.
