When Allies Become Uncertain Anchors

For decades, Europe’s security posture has rested on a quiet assumption: that however turbulent global politics became, the United States would remain the ultimate backstop of the international order it helped create. A new report released ahead of a key European defence conference argues that this assumption can no longer be taken for granted — and that Europe must now be prepared to stand up not only to rivals, but to Washington itself.

The report warns that President Donald Trump and what it calls his cadre of “demolition men” are actively dismantling the post-World War II system of alliances, rules, and institutions that have underpinned European security for generations. Rather than reforming a strained order, the authors argue, U.S. policy is accelerating its erosion through transactional diplomacy, unpredictable commitments, and open skepticism toward multilateral cooperation.

At the center of the critique is a shift in how power is exercised. Where previous U.S. administrations treated alliances as strategic assets, the report says, Trump’s approach frames them as liabilities unless they deliver immediate returns. Tariffs on allies, conditional security guarantees, and fluctuating support for Ukraine are cited as evidence of a worldview that prizes leverage over trust.

For European security experts, the danger lies not in any single policy decision, but in the cumulative effect. An order built over decades can be weakened quickly if its guarantor is seen as unreliable. The report argues that this uncertainty emboldens adversaries, fragments coordination among allies, and forces European states into reactive rather than strategic positions.

The authors stop short of calling for a rupture with Washington. Instead, they urge Europe to adopt a firmer, more self-confident stance — one that treats the transatlantic relationship as a partnership of equals rather than a dependency. That means investing more seriously in defence capabilities, coordinating industrial and military planning, and being willing to resist U.S. pressure when European security interests diverge.

U.S. officials have rejected the characterization of Trump’s policies as destructive, insisting that calls for greater burden-sharing are intended to strengthen, not weaken, the alliance. From Washington’s perspective, Europe’s discomfort reflects overdue adjustments rather than abandonment.

But the report argues that intent matters less than perception. If allies begin to doubt whether commitments will hold, deterrence weakens. In that sense, the authors suggest, the most damaging impact of “demolition politics” is psychological: it replaces predictability with calculation, and solidarity with hedging.

As European leaders gather to debate defence and strategy, the report’s message is stark. The world order Europe grew up within may no longer be preserved by habit or history. Standing up to Trump and his “demolition men,” it concludes, does not mean confrontation for its own sake — but recognizing that stability now requires Europe to act, not wait.
