U.S. Executes Major Policy Shifts: Withdraws from WHO, Restructures Global Health Programs

The U.S. government has implemented sweeping changes to its global health and foreign policy frameworks, including withdrawing from the World Health Organization (WHO) and reevaluating foreign aid programs, according to official directives issued in early 2025. These actions, part of a broader restructuring of U.S. international engagement, reflect a strategic realignment toward what the administration describes as “core American interests.”

Withdrawal from the World Health Organization

The U.S. formally withdrew from the WHO on January 22, 2026, following a directive issued on January 20, 2025, which cited the organization’s handling of the COVID-19 pandemic and alleged mismanagement. The move reverses the Biden administration’s decision to restore funding in 2021, marking a return to a policy initiated under President Trump. According to the White House, the withdrawal “signals a commitment to reasserting American leadership in global health while prioritizing accountability and transparency.” The decision has raised concerns about the WHO’s operational capacity, as the U.S. is the largest single contributor, providing 16%-18% of its annual budget.

Reevaluation of Foreign Aid and USAID Restructuring

A 90-day pause on U.S. foreign assistance, announced in January 2025, triggered legal challenges and operational disruptions. The directive, aimed at aligning aid with “American values,” led to the suspension of programs such as the President’s Emergency Plan for AIDS Relief (PEPFAR) and other global health initiatives. A federal court temporarily blocked the suspension of funding in February 2025, but the administration continued its review. By April 2025, the Department of State began transferring USAID functions to the State Department, culminating in the agency’s dissolution by July 2025. KFF data indicates that 62% of U.S. global health funding is channeled through NGOs, raising questions about the long-term impact of these shifts on public health programs.

Reinstatement of the Mexico City Policy

The Trump administration reinstated the Mexico City Policy, which bans U.S. funding for international NGOs that provide or promote abortion services. This policy, expanded in 2026 under the “Promoting Human Flourishing in Foreign Assistance” framework, now also prohibits support for “gender ideology” and “discriminatory equity ideology.” The move has drawn criticism from global health advocates, who warn it could undermine access to reproductive healthcare in low-income countries. KFF analysis notes that the policy has historically restricted access to family planning services, particularly in regions with high unmet need.

Impact on Global Health Security and Coordination

The elimination of the National Security Council’s Directorate on Global Health Security and Biodefense, a key component of Biden-era reforms, has sparked concerns about gaps in interagency coordination. The move echoes a similar reduction under the Trump administration, which dissolved a similar office in 2018. Experts caution that the absence of centralized oversight could hinder the U.S. response to emerging health threats. CSIS analysis emphasizes the importance of sustained investment in global health security to prevent future crises.

Broader Implications for U.S. Foreign Policy

The administration’s focus on “America First” policies has led to a reevaluation of U.S. participation in multilateral institutions. In addition to the WHO withdrawal, the U.S. announced its exit from 66 international organizations by January 2026, including the U.N. Human Rights Council and UNESCO. These actions reflect a broader strategy to reduce U.S. financial and political commitments to multilateral bodies perceived as misaligned with national interests. State Department statements frame the moves as necessary to “prioritize American sovereignty and security.”

Looking Ahead: Legal and Operational Challenges

Legal battles over the foreign aid freeze and USAID restructuring continue, with courts weighing the balance between executive authority and legislative oversight. The Supreme Court’s decision to allow the administration to proceed with staff reductions and program cuts underscores the complex interplay between policy implementation and judicial review. As the 180-day review of U.S. participation in international organizations nears completion, the long-term effects of these policies on global health and diplomacy remain to be seen.
