An internal Pentagon email has outlined concrete options for punishing NATO members perceived as insufficiently supportive during the ongoing US-Israel war with Iran, including suspending Spain from the alliance, reviewing US backing for Britain's claim to the Falkland Islands, shifting American troops away from unsupportive nations, and barring 'difficult' countries from key NATO positions. According to Reuters, the email prepared by Pentagon policy chief Elbridge Colby expresses deep frustration that access, basing, and overflight (ABO) rights represent 'just the absolute baseline for NATO,' accusing certain allies of a persistent 'sense of entitlement.' Spain drew particular ire for its socialist government's refusal to permit use of bases like Naval Station Rota or airspace for strikes on Iran, while the UK initially restricted offensive operations from its territory before partially relenting.

The Wall Street Journal reported that the Trump administration is actively exploring plans to relocate US troops from NATO countries deemed unhelpful in the Iran conflict toward more cooperative members, a move that stops short of full withdrawal but aligns with President Trump's repeated threats to exit the 76-year-old alliance absent greater reciprocity. This comes amid a war that erupted on February 28, 2026, with US-Israeli strikes on Iran that led to the closure of the Strait of Hormuz, disrupting global shipping and energy flows. European allies have resisted full involvement, citing risks from Iranian missiles capable of reaching their soil, preferring limited defensive support or post-ceasefire assistance.

NATO has firmly responded that its founding treaty contains 'no provision for suspension of NATO membership, or expulsion,' while Spanish Prime Minister Pedro Sánchez downplayed the reports as unofficial. British officials reaffirmed sovereignty over the Falklands. Yet these leaked options reveal a deeper US strategic shift under Trump and Defense Secretary Pete Hegseth toward transactional alliances. Defense officials have stated the war has 'laid bare' the limits of NATO, with Hegseth noting that 'you don't have much of an alliance' without mutual support in crisis.

This approach signals Washington's willingness to fracture NATO's unity to enforce compliance, potentially escalating toward wider conflict. By alienating key European partners over the Iran campaign, the US risks eroding the collective defense posture that deters adversaries like Russia and China. Connections often missed include how punishing NATO 'freeloaders' in a Middle East war could accelerate European strategic autonomy efforts, weaken Article 5 credibility, and embolden Iran-aligned proxies or peer competitors to test divided Western resolve. Rather than strengthening deterrence, such punitive measures may isolate the US, forcing unilateral escalations or concessions that broaden the theater of war from the Persian Gulf to the South Atlantic or Eastern Europe. As one official summarized to Reuters, the goal is decreasing European entitlement—but at what cost to the post-WWII order?
