TLDR

  • Major NATO members have declined participation in US military operations in the Strait of Hormuz
  • European officials characterize the Iran conflict as outside NATO’s defensive mandate
  • Brent crude has climbed beyond $100 per barrel following strait disruptions
  • The EU’s Aspides naval operation remains limited to its original Red Sea mandate
  • Trump cautions that NATO’s future looks uncertain without allied cooperation on his request

Military operations against Iran by the US and Israel have been underway since February 28. The Strait of Hormuz handles approximately 20 percent of global oil transit and has experienced significant closure. Brent crude prices have exceeded $100 per barrel.

Trump issued a weekend appeal for NATO partners to deploy naval vessels for waterway security. European governments largely declined the invitation.

German Foreign Minister Johann Wadephul stated Berlin would avoid joining military operations. German Defence Minister Boris Pistorius delivered a clear message: “This is not our war. We have not started it.”

German Chancellor Friedrich Merz’s spokesman characterized the conflict as falling outside NATO’s scope, describing the alliance as focused on “the defence of territory.”

European Leaders Push Back

UK Prime Minister Keir Starmer clarified that the Strait of Hormuz mission was always planned outside NATO structures and affirmed the UK would avoid wider conflict involvement. He mentioned ongoing discussions about deploying mine-hunting drones already stationed regionally.

Greece, Italy, the Netherlands, and Lithuania all voiced concerns. Dutch Prime Minister Rob Jetten characterized a quick mission launch as “very difficult” to accomplish successfully.

Estonia and Lithuania indicated willingness to examine the US request while seeking clearer operational objectives. Estonian Foreign Minister Margus Tsahkna posed the question: “What will be the plan?”

Denmark’s foreign minister advocated maintaining an “open mind” regarding navigation freedom in the strait, while declining to support the US-Israeli military campaign against Iran.

Poland indicated readiness to evaluate any official NATO request submitted through proper diplomatic channels.

Oil Markets and Crypto React

Oil prices exceeding $100 per barrel have disrupted energy markets. EU foreign policy chief Kaja Kallas noted the strait’s closure benefits Russia’s Ukraine war effort through elevated energy revenues.

The EU’s Aspides mission, established in 2024 for protecting vessels from Houthi threats in the Red Sea, remains unchanged in scope. Following Brussels consultations, Kallas reported zero interest in expansion.

France proposed potential Aspides mission expansion and indicated possible vessel contribution. Trump stated French President Macron expressed French willingness to provide assistance.

On Tuesday, Trump declared via Truth Social that American forces no longer required NATO assistance, emphasizing “WE NEVER DID.” He announced Secretary of State Marco Rubio would identify participating countries.

Trump cautioned in a Financial Times interview that NATO confronts an uncertain future without positive responses to his proposal.
