EU officials are drafting a blueprint for the bloc’s mutual assistance clause as tensions rise over US criticism of NATO allies regarding the Iran war.

European Union leaders have begun drafting a formal blueprint to clarify how the bloc’s mutual assistance clause, Article 42.7 of the EU treaty, would function in the event of a foreign attack [1]. This initiative follows intensifying criticism from the United States regarding the transatlantic alliance and the refusal of several European nations to support US military operations in Iran [1].

**Key takeaways**
* EU leaders are designing a handbook to operationalize Article 42.7, which mandates that member states provide aid and assistance to a country under attack [1].
* The US has expressed frustration over allies’ refusal to grant access, basing, and overflight rights for its military strikes on Iran [1].
* Reports suggest the US has considered retaliatory options, including the suspension of Spain from NATO, though officials note the alliance's treaty lacks an expulsion mechanism [1].
* NATO European members and Canada have committed to increasing defense spending to 5% of GDP by 2035 [2].

## Developing an Operational Defense Blueprint
The push to define the EU’s mutual assistance clause comes as the transatlantic relationship faces its most significant crisis in decades [1]. While Article 42.7 was previously viewed as a flexible tool—having been triggered only once by France following the 2015 Paris attacks—member states now report uncertainty regarding its practical application [1]. Cypriot President Nikos Christodoulides noted that the new blueprint aims to establish an operational plan, addressing questions such as which nations would respond first and how specific requests for aid would be handled [1].

The urgency of these discussions is underscored by a recent drone strike on a British base in Cyprus, which served as a test case for regional cooperation [1]. While some EU officials emphasize that NATO remains the "bedrock of collective defence," they argue that the EU possesses complementary tools, such as financial assistance, sanctions, and humanitarian aid, that could be deployed alongside military efforts [1]. EU diplomats are scheduled to hold tabletop exercises in May to simulate various scenarios for triggering the clause [1].

## Transatlantic Friction and Military Spending
Tensions between Washington and its European allies have been exacerbated by the US-led war in Iran [1]. US Secretary of State Marco Rubio stated that the Trump administration is "disappointed" with the response of NATO members to its Middle Eastern operations, signaling that the issue will be a primary focus at the upcoming NATO summit in Ankara [2]. Despite reports of an internal Pentagon memo outlining potential retaliatory measures against "difficult" allies, Spanish Prime Minister Pedro Sánchez maintained that Spain remains a loyal member of the alliance and operates within the framework of international law [1].

Amid these diplomatic strains, European nations are accelerating efforts to bolster their military capabilities independently of Washington [2]. Germany has authorized a €1 trillion investment in military infrastructure over the next decade, and European NATO members have committed to reaching a 5% GDP defense spending target by 2035 [2].

## Why it matters
The ongoing friction highlights a potential shift in the post-World War II security architecture as European powers seek to secure their strategic interests independently of the United States [2]. While the EU attempts to formalize its mutual defense mechanisms, the project faces internal caution from members concerned about undermining NATO’s collective defense clause [1]. The upcoming NATO summit in Turkey is expected to be a critical juncture for addressing these deepening divisions and the future of the transatlantic alliance [2].
