Unilateralism and Strategic Realignment: The Impact of Trump’s Military Policy on Global Security and Alliances

Abstract

This article examines the impact of the new U.S. military policy under the Trump administration on international relations. Marked by a shift towards unilateralism and transactional alliances, this policy has disrupted traditional multilateral frameworks, weakening the United States' role as a guarantor of global security. By reducing military commitments and pressuring allies to assume greater responsibility for defense spending, the U.S. has forced a rethinking of security strategies among its partners. The article explores how these changes have affected regional security dynamics, particularly in the Middle East, Europe, and the Asia-Pacific region. The withdrawal from multilateral agreements, such as the Iran Nuclear Deal and the reduction in U.S. peacekeeping roles, has created vacuums that other powers, notably Russia and China, have sought to fill. The article further analyzes the responses of U.S. allies, including efforts by Europe to foster greater autonomy in defense and the strengthening of security ties in the Indo-Pacific region. In conclusion, the article argues that the Trump administration's military policy has significantly reshaped global alliances and security dynamics, creating both challenges and opportunities for future international relations.
