Overview

Withdrawing from International Organizations and Treaties

The scope of the January 7 action was striking. Based on the State Department review, the United States identified 66 organizations, conventions, and treaties from which it would be withdrawing, covering a wide range of missions from climate change protection to peace and security, with 17 of the 66 relating to environment, climate change, resources, or sustainable development. Among others targeted were the UN Entity for Gender Equality and the Empowerment of Women, the UN Democracy Fund, and the International Law Commission.

The climate-related withdrawals drew particular attention. These included the Intergovernmental Panel on Climate Change, the International Union for Conservation of Nature, and the UN Framework Convention on Climate Change, the primary global treaty for coordinating international climate action. The UNFCCC withdrawal was historically significant: the U.S. had never before withdrawn from the UNFCCC, a treaty that every nation in the world has joined and that had been upheld by Democratic and Republican administrations alike.

The January 2026 action was itself the third major multilateral withdrawal of Trump's second term, following a pattern set from the first day of his return to office. On January 20, 2025, Trump had withdrawn the United States from the Paris Agreement, calling it an "unfair, one-sided rip-off." He also signed an executive order on that first day mandating withdrawal from the World Health Organization. The United States had been the WHO's largest financial contributor, and the withdrawal raised immediate concerns about implications for global health infrastructure. The January 2026 memorandum built directly on these earlier steps, extending the same logic across the full landscape of U.S. multilateral engagement.

The administration's stated rationale was consistent throughout. Secretary of State Marco Rubio characterized the targeted institutions as "redundant in their scope, mismanaged, unnecessary, wasteful, poorly run, captured by the interests of actors advancing their own agendas contrary to our own, or a threat to our nation's sovereignty." The White House framed the withdrawals as ending American taxpayer funding for entities that advance globalist agendas over U.S. priorities, or that address important issues inefficiently or ineffectively. A review of additional international organizations was described as ongoing at the time of the announcement.

Significance and Impact

The breadth of the January 7 action set it apart from past episodes of American multilateral skepticism. Prior withdrawals—such as the first Trump administration's exit from the Paris Agreement or the U.S. refusal to ratify the Kyoto Protocol—were significant but discrete. The 2026 memorandum represented a comprehensive reassessment of the entire architecture of U.S. participation in international governance, executed through executive action alone.

The climate consequences were seen as especially consequential. The United States is the world's largest historic emitter of greenhouse gases, and its exit from the UNFCCC and other climate agreements ends U.S. participation in the annual Conference of the Parties, cedes international climate leadership to China and the EU, and eliminates any U.S. influence over prospective climate rules, transparency frameworks, and adaptation finance. The U.S. officially exited the Paris Agreement in June 2026, a year after the withdrawal notification was formally submitted.

The financial implications were also significant. The U.S. also withdrew its financial participation from several Just Energy Transition Partnership agreements with South Africa, Indonesia, and Vietnam, canceling over $1 billion in commitments to South Africa and over $3 billion to Indonesia and Vietnam. More broadly, the cumulative effect of the withdrawals removed substantial American funding from a wide range of UN bodies and intergovernmental agencies, altering the operating budgets of institutions that had long relied on U.S. contributions.

America's long-term and structural retreat from the international climate regime is also expected to reverberate at the international level, with some analysts warning that withdrawal may force the world toward a fragmented landscape of bilateralism and climate clubs.

Reactions and Debate

International reaction was swift and largely critical. UN Secretary-General António Guterres expressed regret over the decision, while underscoring that the UN system would continue to deliver on all its mandates. French President Emmanuel Macron condemned the United States for "breaking free from international rules" and "gradually turning away" from its allies. European governments broadly viewed the action as a further erosion of the postwar rules-based order that the United States had done much to build.

Domestic opposition was concentrated among Democrats and within the scientific community. Congressional Democrats decried the move as damaging to American leadership, and the Senate Foreign Relations Committee's ranking member issued a formal statement opposing the withdrawals. Analysts at the National Security Archive characterized the move as a sharp divergence from past Republican presidential administrations that had sought to lead international environmental efforts and establish a comprehensive U.S. climate policy.

The most technically contested aspect of the action was its constitutional legitimacy. The withdrawal from the UNFCCC revived two long-standing but unresolved constitutional questions: whether a president can unilaterally terminate a Senate-ratified treaty, and whether a future president could unilaterally rejoin it. Legal analysts noted the particular sensitivity of using a presidential memorandum to exit a treaty that had been ratified by a two-thirds Senate majority. The U.S. Constitution makes no reference to exiting international bodies and agreements, the Supreme Court has not ruled on the issue, and some legal scholars argue that the president has no general unilateral power to do so. Whether Trump can legally pull the United States out of the UNFCCC without Senate consent remains unresolved.

Supporters of the administration's approach argued that the U.S. had long paid a disproportionate share of the costs of international institutions while receiving inadequate returns, and that the withdrawal from bodies focused on labor, migration, and gender policy reflected democratic accountability to American voters who had elected Trump on an "America First" platform.

Outlook

As of August 2026, the withdrawals are proceeding as directed, though the pace and legal finality of individual exits vary across the 66 organizations. For UN entities specifically, withdrawal was defined as ceasing participation in or funding to those entities to the extent permitted by law —a qualification that acknowledges the legal complexity of some commitments. The UNFCCC withdrawal in particular remains legally contested, and no court has yet resolved whether unilateral executive termination of a Senate-ratified treaty is constitutionally permissible.

Legal scholars have also raised the question of whether a future administration would be able to rejoin the UNFCCC without the need to seek new consent from Congress —a question that could shape the practical reversibility of the January 2026 action. The Biden administration had rejoined the Paris Agreement within days of taking office in 2021; the UNFCCC situation is more complicated, and any future president seeking to restore membership may face a more demanding process.

The broader geopolitical consequences are still unfolding. Some analysts warn that withdrawal may force the world toward a fragmented landscape of bilateralism and climate clubs, and that while the international regime is not expected to collapse, it will become less coherent and will dilute the peer pressure dynamics that multilateral frameworks depend upon. Sub-national actors—U.S. states and cities—have in some cases moved to sustain commitments the federal government has abandoned, but they lack the authority to represent the United States in formal international forums.

The January 2026 memorandum is best understood as a structural expression of a governing philosophy, not merely a list of specific exits. Whether future administrations reverse it, and whether international institutions prove resilient enough to maintain effectiveness without consistent U.S. engagement, are questions that will shape American foreign policy and global governance for years to come.
