Pete Hegseth, the US Secretary of Defense, has reignited transatlantic tensions by renewing criticism of NATO and announcing a comprehensive review of American force posture in Europe. This move, framed as a cost-benefit analysis by Pentagon hardliners, represents a threat vector that European allies cannot ignore. The timing is deliberate: with the Ukraine conflict straining US munitions stockpiles and Beijing’s Pacific ambitions accelerating, Washington is signalling a strategic pivot.
Hegseth’s language echoes the Trump-era disdain for burden-sharing, but the operational reality is more profound. A US drawdown, even partial, would create a critical capability gap in the European theatre. The US provides the bulk of strategic enablers: intelligence, surveillance, reconnaissance, airborne refuelling, and heavy lift.
Without these, NATO’s conventional deterrent against Russia fractures. Britain, ever the loyal ally, has quickly reaffirmed its commitment. The MoD’s statement, however, lacks specifics.
London’s own defence review is overdue, and the British Army is at its smallest since the Napoleonic era. The promise to ‘remain a pillar’ sounds hollow without concrete investments in armour, artillery, and air defence. This is a chess move by Hegseth.
He is testing the alliance’s coherence, knowing that any disunity will be exploited by Moscow. The Kremlin’s information apparatus will amplify every criticism of NATO, framing it as a dying pact. The real danger is not an immediate US withdrawal, but a prolonged review that paralyses allied defence planning.
European capitals must now accelerate their own military modernisation, or risk being left exposed. The hardware calculus is unforgiving: without US logistics and command and control, NATO’s eastern flank is a house of cards. The next few months will determine whether the alliance adapts or fractures.
