US Pushes Europe to Lead Its Own Defence – NATO Shift Towards European Burden‑Sharing (2026)

Overview The United States, for the first time since NATO was created, is asking European members to take primary responsibility for their security. The change is reflected in the U.S. National Security Strategy (Nov 2025) and in the outcomes of the 36th NATO Summit in Ankara (July 2026). Washington wants Europe to fund and field its own conventional forces while it retains the role of a strategic enabler, nuclear guarantor and political convener. Key Developments U.S. urges Europe to raise defence spending to 5 % of GDP as a new benchmark for burden‑sharing . U.S. troop presence in Europe reduced to 75,000‑80,000 personnel, close to pre‑Ukraine‑war levels. At the Ankara Summit, members pledged €70 billion for Ukraine in 2026 and committed to European‑led long‑range precision strike projects and a stronger defence industrial base. Europe agreed to lift core defence spending to at least 3.5 % of GDP by 2035 , with a review in 2029. The U.S. will continue to provide the nuclear umbrella , intelligence, strategic airlift and long‑range strike capabilities. Important Facts Since Russia’s invasion of Ukraine (2022), the U.S. initially increased its European forces to about 100,000 troops, then began a gradual draw‑down in 2025‑26. The shift is not a disengagement but a re‑balancing: Europe will handle conventional defence, while the U.S. remains the strategic enabler . Moscow has responded by reorganising its western military posture, adding new headquarters and bases facing the alliance. UPSC Relevance Understanding this transition is vital for GS 2 (International Relations) and GS 3 (Security & Defence). The concept of Article 5 remains unchanged, but the burden of meeting it is shifting. Aspirants should link the change to India’s strategic calculus: a more self‑reliant Europe frees U.S. attention for the Indo‑Pacific , where India seeks greater security cooperation. Way Forward Europe must develop integrated capabilities: joint command‑and‑control systems, indigenous long‑range strike weapons, and a robust defence industrial base. Simultaneously, India should view the shift as an opportunity to deepen defence‑technology partnerships with both the U.S. and Europe, while preserving its strategic autonomy. Monitoring the pace of European defence reforms and U.S. resource allocation will be key for future policy analysis.
