Europe’s geopolitical debate has changed in one crucial way: it is no longer only about supporting Ukraine, but about surviving a harsher international order. Russia’s war continues to dominate the security picture, yet the larger shock is that Europeans can no longer assume the same level of American backing they took for granted for decades.
That uncertainty has pushed the EU into a more serious conversation about defence and strategic autonomy. The pressure is not abstract. The shift in Washington’s posture has raised fears about NATO burden-sharing, troop deployments, and the long-term reliability of US guarantees. For EU capitals, that has turned security policy from a theoretical ambition into an immediate test of state capacity.
The consequences are visible inside the institutions. MEPs have been pushing for smart defence spending, while policy circles increasingly frame military mobility, critical infrastructure, and industrial resilience as part of the same agenda. Europe is learning, slowly and unevenly, that economic policy and security policy are now intertwined.
This recalibration also exposes the Union’s limits. Member states agree that Europe must do more, but they do not always agree on who pays, who leads, and how far integration should go. That makes the risk of delay high: in a crisis-driven environment, hesitation can become a strategy, even when it produces weakness.
The strategic question for 2026 is no longer whether Europe should build more defence capacity. It is whether the bloc can do so quickly enough to matter, and cohesively enough to avoid replacing one dependence with another.
