伊朗战争没有让跨大西洋关系“瞬间崩盘”，而是像发酵一样逐步变质：对彼此的不满累积、信任流失、旧怨反复被提及。文章强调，3月31日特朗普称盟友在战争初期“不让美国部队用其空军基地或越境飞行”已成导火索，直接把双方从合作关系推向“更接近无法回头点”。
欧洲早期普遍对伊朗行动持谨慎或反对态度，认为其仓促且不明确，并担心被卷入未被征询的战争，但德国、英国最终仍放行了美国基地与空域。作者还指出，丹麦遭威胁、北约成员长期防务支出不足、以及特朗普及其盟友反复发难（如马尔科·卢特4月8日访美未见成效）共同放大了裂痕。
过去六周内，美欧关系受挫最关键的数字是：北约2014年承诺到2% GDP防务支出标准，直到2022年俄乌战争后才被部分重视，而如今只讨论4%或5%并仍遥远于现实。德国与波兰被点名为“仅有按期可达标”的主要欧洲成员，表明“应有”与“现实”差距显著。
The Iran war has not collapsed transatlantic relations overnight but has allowed resentments to curdle into sustained mistrust, with each side building blame narratives after initial friction over base access and airspace. On March 31st, Trump said European allies erred by delaying or denying U.S. operations against Iran and warned they must learn to fight for themselves, reinforcing a perception of strategic rupture.
Despite governments such as Germany and, after hesitation, Britain eventually allowing base and airspace use, European publics feared being dragged into a war they did not endorse, while other pressure points—Denmark, tariffs, and repeated U.S. threats—deepened alienation. Trump’s April 8th efforts by NATO Secretary-General Mark Rutte to keep allies aligned gained little traction, and while Article 5 remains formally intact, its deterrent credibility is described as weaker than at any point in NATO’s 77-year history, with even U.S. officials openly questioning the value of alliance membership.
The hard numbers are central: the 2014 commitment for 2% of GDP defense spending was largely ignored until the 2022 Russian invasion of Ukraine, and discussions of 4% or 5% show how wide the compliance gap remains, with only Germany and Poland reportedly on track. The article argues Europe must move toward sustained higher defense spending, build air defense, logistics, and munitions capacity, integrate force and industrial planning, and place Ukraine—after four years of war and now the continent’s second-largest, battle-hardened force after Russia—at the core of a future security architecture, even if a full reconciliation in the near term looks uncertain after six weeks of escalation.
