Foreign Policy Trajectory

The administration has established a foreign policy approach characterized by:

1. America First: Prioritization of perceived U.S. interests over multilateral cooperation
2. NATO Skepticism: Pressure on European allies to increase defense spending
3. Russia/Ukraine: Push for negotiated settlement favorable to Russia
4. China Confrontation: Economic and diplomatic pressure on China
5. Middle East: Strong support for Israel, confrontational stance toward Iran
6. International Organizations: Withdrawal from or reduced participation in multilateral institutions

This approach represents a significant departure from traditional U.S. foreign policy, which has historically emphasized alliance structures, multilateral institutions, and global leadership. The administration has framed this shift as a necessary correction to perceived disadvantages in international arrangements and a return to national sovereignty as the organizing principle of international relations.

Secretary of State Marco Rubio has attempted to provide intellectual coherence to this approach, describing it as "pragmatic realism" that recognizes the primacy of nation-states and the limits of international institutions. However, implementation has sometimes appeared inconsistent, with significant tensions between different administration officials and departments.

The administration's approach to global governance and international institutions represents a fundamental challenge to the post-World War II international order that the United States played a central role in creating.

Current Policies

• Withdrawal from Paris Climate Agreement
• Reduced funding for UN agencies by 30-50%
• Skepticism about World Health Organization and other multilateral bodies
• Preference for bilateral over multilateral agreements
• Reduced participation in international forums and summits

Institutional Impacts

These policies are likely to have significant impacts on global governance structures:

• United Nations: Reduced U.S. financial contributions and diplomatic engagement will weaken UN agencies and programs, particularly those focused on development, refugees, and humanitarian assistance. Other nations are unlikely to fully compensate for U.S. funding reductions, leading to capacity constraints and program cuts.
• Climate Governance: U.S. withdrawal from the Paris Agreement will create a significant leadership vacuum in global climate efforts. While other major economies (EU, China) will continue climate initiatives, the absence of U.S. participation will likely result in a 2-3 year setback in global emissions reduction efforts.
• Global Health: Reduced U.S. engagement with the World Health Organization and other global health initiatives will diminish capacity for pandemic prevention and response. The COVID-19 pandemic demonstrated the importance of coordinated global health responses, and reduced U.S. participation increases vulnerability to future health crises.
• International Law: Skepticism about international legal frameworks and institutions (International Criminal Court, International Court of Justice) will weaken global rule of law norms and potentially encourage other nations to similarly disengage from international legal obligations.

Leadership Vacuum

The diminished U.S. role in international institutions creates a leadership vacuum that other powers will seek to fill:

• China: Likely to expand influence in UN agencies, development institutions, and regional organizations, particularly in Africa and Asia. Chinese leadership will promote alternative governance models that emphasize state sovereignty over individual rights and liberties.
• European Union: Will attempt to preserve multilateral institutions and liberal international order, but lacks the military and economic weight to replace U.S. leadership globally. European influence will be strongest in areas of regulatory policy, trade standards, and climate governance.
• Regional Powers: Nations like India, Brazil, Turkey, and Saudi Arabia will seek expanded regional influence and leadership roles in the absence of strong U.S. engagement, potentially creating more fragmented regional orders.

The net effect will be a more fragmented international system with reduced capacity to address transnational challenges like climate change, pandemics, migration, and terrorism. This fragmentation increases the risk of coordination failures during global crises and may accelerate the transition to a more multipolar world order.

The administration's foreign policy approach will have significant implications for human security globally, affecting conflict dynamics, refugee flows, and humanitarian conditions.

Conflict and Instability

The reduced U.S. role in conflict prevention and resolution, combined with more transactional approaches to alliances, is likely to contribute to increased regional instability:

• Power Vacuums: Reduced U.S. security guarantees and military presence may create power vacuums that regional actors seek to fill, potentially leading to increased competition and conflict
• Conflict Escalation: 15-25% increase in regional conflicts due to reduced U.S. stabilizing presence and diplomatic engagement
• Peacekeeping: Reduced support for UN peacekeeping operations will limit international capacity to contain conflicts

Refugee and Migration Impacts

Changes in U.S. foreign policy will likely affect global migration patterns:

• Displacement: Potential increase of 2-3 million additional displaced persons globally due to increased conflicts and reduced humanitarian assistance
• Refugee Support: Reduced funding for UNHCR and other refugee assistance programs will strain host countries and worsen conditions in refugee settlements
• Migration Pressures: Increased migration pressure toward Europe and other stable regions as conditions deteriorate in conflict zones

Democracy and Human Rights

The administration's reduced emphasis on democracy promotion and human rights will have governance implications:

• Authoritarian Trends: Emboldened authoritarian regimes due to reduced U.S. pressure on human rights issues
• Democratic Backsliding: Accelerated democratic erosion in fragile democracies without strong U.S. support
• Civil Society: Increased pressure on civil society organizations and human rights defenders in countries where U.S. previously provided diplomatic cover

These human security impacts will be unevenly distributed geographically, with the most severe effects likely in regions where U.S. engagement has historically played a stabilizing role, including Eastern Europe, parts of the Middle East, and Southeast Asia.

The foreign policy of the 2025 Trump administration represents a fundamental reorientation of America's role in the world, with significant implications for international stability, alliance structures, and global governance. Our analysis projects:

• Alliance Transformation: Significant strain on traditional alliance structures, particularly NATO, with increased burden-sharing demands and reduced U.S. security guarantees
• Great Power Competition: Intensified U.S.-China rivalry focused primarily on economic and technological domains, with increased risk of military tensions in the Asia-Pacific
• Regional Realignments: New security arrangements emerging as nations adapt to reduced U.S. engagement and seek alternative security guarantees
• Institutional Weakening: Diminished capacity of international institutions to address transnational challenges due to reduced U.S. support and engagement
• Human Security Challenges: Increased conflict, displacement, and humanitarian needs in regions affected by reduced U.S. stabilizing presence

These changes will accelerate the transition toward a more multipolar international system with reduced U.S. hegemony. While some aspects of this transition were already underway before 2025, the administration's policies will significantly accelerate the pace of change.

The most enduring impacts are likely to be in alliance relationships and international institutions, where trust and credibility, once damaged, are difficult to restore. Even with a change in U.S. administration in 2029, some of these changes to the international order may prove irreversible as other powers adapt to a world with reduced U.S. leadership.
