The United States has initiated a comprehensive review of its military footprint in Europe, a decision that follows repeated criticisms from President Donald Trump regarding the commitment of European allies to the NATO alliance. This strategic re-evaluation, confirmed by US Under Secretary of Defense Elbridge Colby, is intended to propel NATO towards a future where Europe assumes primary responsibility for its conventional defense. Colby articulated that the outcome would be an accelerated transition, fostering a stronger, more equitable, and ultimately more sustainable alliance.
This move was not entirely unanticipated by European leaders. Just last month, US Defense Secretary Pete Hegseth informed NATO counterparts in Brussels of Washington’s intent to conduct such a review. Hegseth explicitly stated that this would be a rigorous assessment, designed to push NATO irreversibly towards European leadership in its own defense. He candidly warned that some nations would likely “fail” this review, while others would “pass with flying colors,” underscoring the seriousness of the impending evaluation.
During his address at NATO headquarters, Hegseth echoed President Trump’s long-standing grievances, particularly regarding what he perceived as an inadequate European response to the joint US-Israeli military actions in Iran. He specifically cited the refusal of some European nations to grant US forces access to bases for potential attack launches, a point of contention that has simmered for months. Furthermore, Hegseth reiterated threats to reduce Washington’s financial contributions to NATO unless member states met agreed-upon defense spending targets, signaling a potential shift in the alliance’s financial burden.
The implications of this review are significant for European allies, who have become accustomed to a degree of American military presence and leadership. German Chancellor Friedrich Merz, speaking last month, acknowledged that European nations had been aware of Washington’s long-term intentions to potentially draw down troops. Merz emphasized the critical need for the European bloc to bolster its own security capabilities, stating, “We know that we must do more and we are doing it.” This sentiment reflects a broader recognition across Europe that a greater degree of self-reliance in defense is becoming increasingly imperative.
In response to this evolving dynamic and the growing uncertainty surrounding Washington’s long-term security commitments, European allies and Canada have already begun to accelerate efforts to strengthen their indigenous defense capabilities. The annual NATO summit in Ankara earlier this month provided a platform for European Commission chief Ursula von der Leyen and NATO Secretary General Mark Rutte to articulate a vision for a more “European” NATO. Both leaders stressed the unsustainability of continued over-reliance on the United States for security. Rutte, in particular, highlighted an “unparalleled” transformation driven by enhanced EU-NATO cooperation, advocating for a much stronger Europe operating within the framework of a stronger NATO. This collective push towards greater European defense autonomy suggests a fundamental recalibration of the transatlantic security architecture may well be underway.
