The war in Ukraine and the shift in U.S. posture have forced Europe to confront a long-avoided reality: continental security can no longer rest exclusively on external guarantees. For decades, the European Union had been able to focus resources on economic integration, delegating defense to an ally considered stable.

This balance has progressively dissolved. The return of high-intensity warfare to European soil and the unpredictability of American politics have marked the end of the illusion that peace was a permanent state.

Rearmament and Pressure on European Societies

Since 2022, Europe has initiated the most significant rearmament process since the end of the Cold War. The increase in military spending has become structural, with investments in munitions, air defense, defense industry, and deterrence.

This process has had direct effects on European societies: reallocation of public resources, return of the debate on mandatory conscription in several countries, and internal political tensions between security and welfare. Rearmament has not been presented as an ideological choice but as a necessity.

Regional Cooperation: Scandinavia as a Laboratory

In the absence of a true European military union, integration advances through regional and functional blocks. The most evident case is Scandinavia and the Baltic area, where military and intelligence cooperation has assumed a de facto integrated dimension.

Finland, Sweden, Norway, Denmark, and the Baltic states increasingly operate as a single strategic space: coordinated planning, force interoperability, intelligence sharing, and joint protection of the Baltic Sea. This integration does not arise from grand political treaties but from operational necessity.

Transatlantic Trust and Danish Security Concerns

In this context, significant institutional signals are emerging. Danish intelligence has included the United States among potential risk factors for security—not as an adversary but as an increasingly unpredictable ally. This is a politically relevant fact: for the first time, a European NATO country formally signals the erosion of transatlantic trust.

This does not indicate a rupture of the alliance but certifies a structural change in risk perception.

Irreversible Decisions: Russian Assets

On the economic and legal front, the European Union has made structural decisions. The choice to make the freezing of Russian sovereign assets permanent, moving beyond periodic renewals subject to veto, marks a historic turning point.

An emergency measure becomes a stable normative state, institutionalizing a long-term fracture with Russia and redefining the concept of financial neutrality.

A More Aware Actor, but Incomplete

In the medium-long term, Europe appears more armed and more aware but still incomplete on the strategic level. Autonomy advances by necessity, not by shared vision. European security is no longer delegable but remains politically and institutionally fragile.
