• US Ambassador to NATO Matthew Whitaker emphasizes European allies must assume greater responsibility for conventional defense, framing this as strengthening NATO.
  • The US is transferring key NATO command posts to European allies, including leadership of Naples command to Italy and Norfolk command to Britain.
  • European nations respond with increased military spending commitments while navigating concerns about US reliability and trade tensions.

A Strategic Shift in Transatlantic Burden-Sharing

US Ambassador to NATO Matthew Whitaker has been clear in recent messaging: the United States wants European allies to take over the conventional defense of the European continent. Speaking at the Munich Security Conference in February 2026, Whitaker rejected characterizations that this approach dismantles NATO, stating instead, "We're trying to make NATO stronger, not to withdraw or reject NATO, but make it work like it was intended as an alliance of 32 strong and capable allies." He framed the US position as "tough love," using an analogy about expecting children to eventually get jobs rather than remain dependent.

This push reflects a broader shift in how the Trump administration views transatlantic burden-sharing, with Whitaker noting that US presidents since Eisenhower have urged Europe to do more for its own defense. However, current efforts appear more forceful, tied to President Trump's broader skepticism about traditional alliances and frustration over what he calls Europe's unfair trade advantages. At Munich, Whitaker cited Europe's "huge surplus with the U.S." and slow decision-making on trade matters as ongoing irritants.

Command Structure Realignment Underway

Concrete steps are already being taken to reallocate military leadership. According to people familiar with the matter, the US will hand over leadership of NATO's Naples command—which oversees the alliance's southern flank—to Italy. Similarly, the Norfolk command covering northern regions will transition to Britain, while the US takes command of NATO's maritime forces based in the United Kingdom. This restructuring aims to "strengthen NATO and enhance operational" capabilities by reducing US dominance in command structures, though it carries risks if European military development lags behind the withdrawal timeline.

Defense Department policy chief Elbridge Colby is expected to discuss the Pentagon's strategy regarding "capabilities that may need to be ultimately transitioned out of Europe" in upcoming meetings. The reallocation suggests a sustained effort to shift military responsibility to European actors, even as Secretary of State Marco Rubio leads a high-level delegation to Munich and visits Slovakia and Hungary to signal continued US engagement.

European Responses and Rearmament Efforts

European allies have responded with a mix of apprehension and action. The Munich Security Conference report warned of an era of "wrecking-ball politics" and noted growing concerns that the US has become a driver of instability, with the transatlantic relationship increasingly marked by "reassurance, conditionality, and coercion." Many European governments are adopting a dual-track approach: keeping the US closely engaged while simultaneously building greater capacity to act independently through rearmament.

European countries have already ramped up military budgets following Russia's invasion of Ukraine and agreed last year to hike NATO's defense spending targets. Whitaker criticized what he called "a lot of discussion and not a lot of action" among some allies, though he singled out Germany for demonstrating genuine commitment to rearmament. At the June 2025 NATO summit in The Hague, European nations proposed a formula for increased military spending, which the US viewed as a success.

Implications and Future Outlook

The push for European defense burden-sharing comes amid heightened tensions. Trump's recent claims about Greenland and broader rhetoric have "rattled faith in the reliability of the United States" and momentarily "plunged the alliance into crisis," according to conference attendees. Whitaker distanced himself from Trump's inflammatory statements on Greenland while defending the underlying security rationale regarding Russian and Chinese influence in the region.

Looking ahead, the Munich Security Conference report emphasized that Europe must prepare for a future where "American support remains important, but can no longer be taken for granted." If European military capability development lags behind the US withdrawal timeline, NATO's overall deterrent capacity against Russia could suffer during a critical period. However, the command post transfers indicate a deliberate restructuring intended to foster greater European leadership in conventional defense, aligning with Whitaker's assertion that this effort strengthens rather than weakens the alliance.
