America is currently experiencing a period of heightened skepticism toward multilateral institutions. As President Trump has withdrawn the United States from 31 UN bodies that he believes operate contrary to American interests, debates about the United States’ role in the United Nations have resurfaced and become prominent in American political discourse. Some people interpret proposals to withdraw from UN bodies as efforts to preserve national sovereignty or reduce financial and political obligations. However, a critical analysis of U.S. strategic, diplomatic, and normative interests suggests that strengthened participation in the United Nations remains essential to advancing American influence and global stability.
An important reason why America should enhance its participation in the UN is that the United Nations offers the United States an unparalleled platform to enhance global security outcomes in an increasingly interdependent world. As a permanent member of the UN Security Council, the United States holds veto power over resolutions related to peacekeeping missions, sanctions regimes, and responses to armed conflict. This position enables American politicians to not only block initiatives that run counter to American interests but also to shape the international community’s approach to emerging crises. Withdrawal from the UN would not simply eliminate global security challenges; rather, it would remove the United States from the primary forum in which those challenges are debated and addressed.
Additionally, strengthened American engagement in the United Nations strengthens U.S. coordination and collaboration with its allies, particularly its strongest European allies, such as the U.K. While the United States and Western European partners often have conflicting political interests, the UN serves as a critical venue for negotiation, consensus-building, and compromising on important matters. Through multilateral cooperation, the United States can pursue shared objectives, such as conflict prevention and post-conflict reconstruction, while improving partnerships with Western Europe to create stronger socio-political outcomes for themselves and for the rest of the world. Absent this institutional framework, transatlantic cooperation would become less effective over time and would likely weaken alliances that have underpinned international stability since the mid-twentieth century.
Moreover, increased U.S. participation in the United Nations reinforces international norms related to democratic governance, political accountability, and human rights. Although the UN is regularly criticized for its limitations and inconsistencies, it is a central mechanism through which norms are articulated, monitored, and, in some cases, enforced. American engagement enables the United States to advocate for political freedoms and protections for civilians within multilateral bodies, such as the General Assembly and Human Rights Council. While these efforts do not always yield immediate outcomes, disengagement would reduce U.S. leverage and leave norm setting processes increasingly shaped by states with fewer commitments to
liberal democratic principles.
Enhanced United Nations membership also enhances the political legitimacy of American foreign policy actions. When the United States operates through multilateral institutions, its initiatives are more likely to be understood as cooperative rather than unilateral, which reduces the likelihood of diplomatic backlash and increases global compliance. This legitimacy is
particularly important in addressing transnational challenges, such as global health threats and refugee flows, which cannot be effectively managed by any single country. The UN provides coordination mechanisms that amplify U.S. efforts while aligning them with broader international support.
Finally, American withdrawal from the United Nations would create opportunities for rival states, such as Russia and China, to expand their influence within the institution. By remaining engaged, the United States can ensure that it continues to shape rules, norms, and agendas that will affect international politics regardless of its participation. By contrast, political
disengagement risks undermining long-term American interests while diminishing the country’s ability to respond to future crises.
While the United Nations is an imperfect institution, continued U.S. membership is paramount for advancing American security, diplomatic influence, and normative objectives. Rather than withdrawing from it, the United States should pursue reform and sustained engagement. This way, it can use its position within the UN to promote stability, cooperation, and a rules-based international order to generate stronger socio-political outcomes for its citizens, its allies, and the rest of the world.
