文章以美国《2025年国家安全战略》（文中日期为2025年12月15日）为线索，对比哈贝马斯1998年提出的「后民族」欧洲想像：在二战与20世纪上半叶的族裔民族主义灾难（走向大屠杀）之后，透过超国家制度与「宪政爱国主义」淡化血缘、吸纳移民，并让「旧欧洲」（欧盟后来的6个创始国）走向更紧密的联盟。

作者指出，这种后民族愿景从未成为共识：刚从多重帝国统治脱身的「新欧洲」更想打造族裔民族国家，匈牙利的欧尔班被视为极端例子；在「旧欧洲」，对来自非洲、亚洲与中东的移民与难民的排斥，推动极右政党崛起。美国自身也沿著不同起点走向相似争论，而特朗普与MAGA的两次兴起，使「谁算更美国」的排他叙事在政策圈占上风，文中点名史蒂芬·米勒与副总统JD·万斯（并提到他在2月慕尼黑安全会议的表态）。

文章认为新战略文件颠覆了战后传统：对俄罗斯、中国等威权对手语义上偏中性，对中东穆斯林与阿拉伯伙伴则承诺不再「训斥」，却对欧盟与主流民主政治人物充满敌意，甚至主张扶持欧洲「爱国政党」。它指控超国家机构削弱主权、指控欧洲「审查」言论，并以移民引发「身份流失」渲染欧洲在「不超过20年」内将面目全非；作者据此警告，美国等同宣示将介入欧洲内政，成为民族主义回潮的新盟友。

Using the 2025 US National Security Strategy (dated Dec. 15, 2025), the piece contrasts today’s Washington with Juergen Habermas’s 1998 post-national vision for Europe: after the hyper-nationalism of the first half of the 20th century culminated in total war and the Holocaust, Europeans—backed by the US—would move beyond ethnic identity through supranational institutions and “constitutional patriotism,” with “Old Europe” (the EU’s six founding states) heading toward an ever-closer union.

It argues that post-nationalism was never a stable consensus. “New Europe,” emerging from successive empires, often preferred building ethnically rooted nation-states, with Orban’s Hungary as a leading example; across the continent, far-right parties have gained influence. The US followed a parallel but differently rooted debate over who counts as fully American, and the Trump/MAGA era sharpened nativist answers; the article highlights Stephen Miller and Vice President JD Vance, citing Vance’s February Munich Security Conference speech as signaling affinity with Europe’s blood-and-soil right.

The Strategy, the author says, flips postwar habits: it is comparatively mild toward autocratic Russia and China, promises to stop “hectoring” Muslim and Arab partners in the Middle East, yet turns vitriolic toward mainstream democratic leaders in Old Europe while courting the far-right fringe. It claims the EU “undermines” liberty and sovereignty, alleges “censorship,” and portrays immigration as erasing national identities so thoroughly that Europe will be “unrecognizable in 20 years or less.” Most starkly, it calls for “cultivating resistance” and aiding “patriotic European parties,” which the author frames as an official pledge of US meddling in Europe’s domestic politics.
