TLDR
- Major European NATO members have declined to participate in US military operations in the Strait of Hormuz
- German and British officials characterize the Iran conflict as outside NATO’s defensive mandate

- The European Union’s Aspides naval operation remains limited to its current Red Sea mission
- President Trump issues warning about NATO’s future if member states refuse cooperation
Since late February, American and Israeli forces have engaged in military actions targeting Iran. The Strait of Hormuz—a critical chokepoint handling roughly 20% of global oil shipments—has experienced significant disruption. Crude oil prices have surged beyond the $100 per barrel threshold.
Over the past weekend, President Trump requested that NATO partner nations contribute warships to establish security in this vital waterway. The majority of European governments declined the request.
Johann Wadephul, Germany’s Foreign Minister, stated that Berlin has no plans to participate in these military actions. Boris Pistorius, the German Defence Minister, was unequivocal: “This is not our war. We have not started it.”
A spokesperson for German Chancellor Friedrich Merz emphasized that the situation has “nothing to do with NATO,” describing the alliance as “an alliance for the defence of territory.”
European Leaders Push Back
British Prime Minister Keir Starmer clarified that operations in the Strait of Hormuz were never intended as a NATO initiative and affirmed the UK would “not be drawn into the wider war.” However, he noted Britain is discussing the potential deployment of mine-detection drones already positioned in the region.
Several other nations including Greece, Italy, the Netherlands, and Lithuania have voiced concerns. Dutch Prime Minister Rob Jetten indicated it would be “very difficult to launch a successful mission there in the short term.”
Baltic nations Estonia and Lithuania suggested allies should evaluate the American request while seeking greater clarity on objectives. Margus Tsahkna, Estonia’s Foreign Minister, questioned: “What will be the plan?”
Denmark’s top diplomat suggested Europe maintain an “open mind” regarding navigation freedom through the strait, despite not supporting the US-Israeli decision to initiate hostilities with Iran.
Poland indicated willingness to carefully evaluate any formal NATO proposal if submitted through proper diplomatic channels.
Oil Markets and Crypto React
Oil prices exceeding $100 per barrel have destabilized energy markets worldwide. Kaja Kallas, the EU’s foreign policy chief, noted that the strait’s disruption benefits Russia’s Ukrainian campaign through elevated energy revenues.
The European Union’s Aspides operation, launched in 2024 to safeguard maritime traffic from Houthi threats in the Red Sea, has not been expanded. Following discussions in Brussels, Kallas indicated there was “no appetite” for broadening its scope.
France proposed that the Aspides mission could potentially be expanded and suggested it might contribute a vessel for support operations. Trump claimed French President Macron assured him of France’s willingness to assist.
On Tuesday, Trump posted on Truth Social declaring the US no longer required NATO assistance, stating that “WE NEVER DID.” He announced that Secretary of State Marco Rubio would identify which countries are prepared to provide support.
Trump also cautioned in a Financial Times interview that NATO confronts a “very bad” future if member nations fail to respond to his proposal.
