Some European defense officials are pushing back on efforts to cut US tech reliance, warning it could leave Europe with inferior systems and greater cyber risks
Context & Ripple Effects
European military officials had already warned in February that technology-sovereignty proposals could carry security costs because armed forces depend on US software and networks. The dispute has widened from a defense concern into a broader policy conflict: Brussels was drafting sovereignty legislation while EU banks and manufacturers warned of competitiveness and profit effects.
The defense officials’ intervention makes cyber resilience and system quality explicit tests for any effort to reduce US dependence, rather than treating supplier nationality as a sufficient security criterion. It also sharpens a tension with the EU’s separate effort to phase out Huawei from critical infrastructure.
First-order effects
- European defense procurement teams face pressure to preserve access to established US technology where officials judge European substitutes less capable or less secure.
- EU technology-sovereignty plans must contend with a defense constituency arguing that a rapid vendor shift can itself increase cyber exposure.
Second-order effects
- US software, network and cloud suppliers retain leverage in European defense-related procurement while officials contest whether alternative suppliers meet operational and security requirements.
- Brussels’ sovereignty agenda faces a harder coordination problem across defense, civilian industry and cybersecurity policy, after business groups warned of competitiveness costs as well as military officials raised security concerns.
Third-order effects
- If security and performance become formal procurement criteria, European sovereignty policy is likely to evolve toward diversified, interoperable supply rather than a simple replacement of US vendors.
- The episode points to coordination sovereignty: Europe’s strategic autonomy will depend on whether it can build credible alternatives without weakening the interconnected systems its military and businesses rely on.
The trend: European tech sovereignty is becoming a resilience-and-capability balancing exercise, not merely a drive to substitute domestic suppliers for US ones.
