Europe Must Build Its Own Defense as U.S. Commitment Erodes

Shift from U.S.-guaranteed European security architecture toward independent European defense capabilities. Germany emerging as de facto European security leader. Weakening of transatlantic alliance cohesion and NATO Article 5 credibility. U.S. using security commitments as economic/political coercion rather than strategic consensus.

Similar to 1930s erosion of collective security frameworks (League of Nations) when great powers weaponized commitments, forcing smaller states toward self-reliance and regional blocs, ultimately destabilizing the international order.

European households face potential higher taxes for increased defense budgets (Germany targeting 3.5% of GDP by 2029), increased inflation from military procurement, and possible economic disruption from reduced U.S. security guarantees affecting investment confidence and employment in defense-dependent regions.

European governments will accelerate autonomous defense capabilities, increase military R&D investment, potentially form independent defense procurement frameworks, negotiate alternative security arrangements, and may implement protectionist policies favoring domestic defense industries. Likely EU-level coordination on defense spending and industrial policy.
