Pentagon Briefs Allies on 2026 Plan to Shrink U.S. NATO Assets by One-Third to One-Half

NATO has weathered sudden American pullbacks before—the 1966 French exit from the alliance’s integrated command forced relocation of NATO headquarters within two years, and the 1973 post-Vietnam troop cuts saw U.S. Army strength in Europe fall from 277,000 to 175,000 by 1975—yet the alliance ultimately adapted through greater European spending and new force structures. The 2026 reduction fits a 15-year U.S. “pivot” away from Europe toward China and the Indo-Pacific, a trend codified in the 2012 Defense Strategic Guidance and accelerated by bipartisan administrations. It also echoes a century-long pattern: as hegemonic burdens grow unsustainable, the leading power pressures allies to shoulder more costs (think British imperial retrenchment east of Suez in 1968). Whether this moment proves inflectional depends on Europe’s reaction; if the EU and U.K. translate recent 5 %-of-GDP pledges into real capabilities, NATO could emerge more balanced, but if political fragmentation stalls rearmament the drawdown may invite strategic opportunism from Russia and others. On a 100-year arc, the episode signals the steady normalization of a multipolar system where U.S. power is still considerable but no longer automatically underwriting every theater simultaneously.
