A remark by US Defense Secretary Pete Hegseth comparing irregular migration to the D-Day landings has triggered a diplomatic row, with a Whitehall source describing the comment as evidence of Washington’s growing contempt for European sovereignty. Speaking at a Pentagon press conference on Wednesday, Hegseth said the influx of migrants across the English Channel was ‘a logistical invasion as significant as any since 1944’. The analogy, which drew immediate condemnation from French and German officials, reflects a broader shift in US strategic thinking towards the continent, according to British diplomatic insiders.
The Whitehall source, who spoke on condition of anonymity, said Hegseth’s rhetoric ‘lays bare the structural weaknesses in Europe’s border architecture and the absence of a unified deterrent’. The source added that the comment ‘will be read in Moscow and Beijing as a signal that the US views its European allies as incapable of managing their own periphery’. The remark comes amid stalled talks on a UK-EU returns agreement and rising Channel crossing numbers: over 29,000 migrants have arrived via small boats this year, a 15% increase on the same period in 2024.
Hegseth’s framing echoes language used by the Trump administration, which repeatedly characterised migration flows as an ‘invasion’. However, his direct invocation of the Normandy landings marks a significant escalation. The comparison was condemned by French Defence Minister Sébastien Lecornu, who called it ‘a false equivalence that insults the memory of Allied soldiers’. German Chancellor Olaf Scholz’s spokesman declined to comment directly but noted that ‘migration is a challenge, not a war’.
Analysts suggest the incident reflects a broader US strategy to pressure European states into hardening border policies. ‘Washington is openly weaponising historical memory to force a policy shift,’ said Professor James Dillon of the Royal United Services Institute. ‘It’s a calculated breach of diplomatic protocol, designed to embarrass allies into action.’ The UK Foreign Office has issued no formal response, but Downing Street sources indicate Prime Minister Sir Keir Starmer raised the matter with US national security adviser Jake Sullivan during a call on Thursday.
The episode underscores the fragility of transatlantic ties amid the Biden administration’s shifting focus to the Indo-Pacific. With the US assuming its European partners can no longer secure their own borders, Whitehall fears ‘strategic abandonment’ in favour of a more transactional relationship. ‘Hegseth’s language is a symptom of a deeper malaise,’ the Whitehall source said. ‘Europe is being recast as a liability, not an asset.’ The source added that the UK, despite Brexit, remains ‘uniquely exposed’ due to its geographic position and reliance on US intelligence sharing.
French President Emmanuel Macron is expected to address the issue during a scheduled visit to London next week, but diplomats predict only a vague joint statement. ‘There is no appetite for a formal protest,’ a senior EU diplomat said. ‘Everyone is afraid of triggering a trade war.’ The incident has revived debate over the proposed UK-Rwanda asylum plan, which Hegseth reportedly praised in private. No details of the conversation have been released.
For now, the Whitehall assessment is grim: Hegseth’s words have dealt a blow to European credibility, and the silence from Brussels and London only compounds the damage. The question of whether Europe can craft a coherent response to both migration and US pressure remains unanswered.
