TLDR
- European NATO members have declined participation in U.S. military operations in the Strait of Hormuz
- Germany and other European nations maintain the Iran conflict does not fall under NATO’s defensive mandate
- Crude oil has surged past $100 per barrel following the strait’s effective closure
- The European Union has not expanded its existing Aspides naval operation to this region
- Trump issued warnings about NATO’s future following the rejection of his deployment request
Military actions against Iran by the United States and Israel have been ongoing since late February. The strategic Strait of Hormuz, a critical chokepoint handling approximately 20% of global oil traffic, has experienced severe disruptions. Crude prices have breached the $100 per barrel threshold.
During the weekend, Trump appealed to NATO partners to deploy naval vessels for securing the strategic waterway. The majority of European nations declined the request.
Johann Wadephul, Germany’s Foreign Minister, stated that Berlin would not participate in military actions. Defence Minister Boris Pistorius was unambiguous in his response: “This is not our war. We have not started it.”
A spokesperson for Chancellor Friedrich Merz emphasized that the situation has “nothing to do with NATO,” describing the alliance as one focused on “the defence of territory.”
European Leaders Push Back
British Prime Minister Keir Starmer clarified that NATO never intended the Strait of Hormuz operation as an alliance mission and stated the UK would “not be drawn into the wider war.” However, he acknowledged ongoing discussions about deploying UK mine-hunting drones currently stationed in the area.
Several nations including Greece, Italy, the Netherlands, and Lithuania voiced concerns about the proposal. Dutch Prime Minister Rob Jetten emphasized it would be “very difficult to launch a successful mission there in the short term.”
The Baltic states of Estonia and Lithuania indicated willingness to review the American request but emphasized the need for additional details regarding objectives. Estonian Foreign Minister Margus Tsahkna questioned: “What will be the plan?”
Denmark’s top diplomat suggested Europe should maintain an “open mind” regarding navigation freedom in the strait, despite not supporting the U.S.-Israeli military campaign against Iran.
Poland indicated it would give serious consideration to any official NATO request submitted through proper diplomatic channels.
Oil Markets and Crypto React
Oil prices exceeding $100 per barrel have created volatility in energy markets. Kaja Kallas, the EU’s foreign policy chief, noted that the strait’s disruption was generating additional revenue for Russia’s military operations in Ukraine through elevated energy prices.
The European Union’s Aspides operation, established in 2024 to safeguard commercial shipping from Houthi attacks in the Red Sea region, has not received authorization for expansion. Following discussions in Brussels, Kallas reported there was “no appetite” for extension.
France proposed potentially expanding the Aspides mission’s scope and indicated possible vessel contributions for support operations. Trump claimed French President Macron confirmed France’s willingness to provide assistance.
By Tuesday, Trump declared on Truth Social that American forces no longer required NATO assistance, asserting that “WE NEVER DID.” He announced that Secretary of State Marco Rubio would publicly identify which nations were prepared to contribute.
In a Financial Times interview, Trump cautioned that NATO confronts a “very bad” outlook if member states fail to respond to his deployment proposal.
