Germany wants to examine the final terms of Washington’s agreement with Tehran before joining a European maritime mission aimed at protecting shipping through the strategic waterway.
Germany has declined to commit forces to a proposed maritime security operation in the Strait of Hormuz until it has examined the full terms of the emerging agreement between the United States and Iran.
Berlin’s cautious position underlines the political and legal uncertainty surrounding European plans to safeguard one of the world’s most important energy corridors following months of conflict and disruption to commercial shipping.
German officials have indicated that the nature of any European deployment must depend on what Washington and Tehran have actually agreed, particularly regarding the reopening and future administration of the strait.
Although the United States and Iran have announced an interim framework intended to halt hostilities and restore maritime traffic, important questions remain about how the accord will be implemented and monitored.
Germany wants to establish whether a separate naval operation would support the diplomatic agreement or risk complicating it by introducing additional foreign military forces into waters that Iran considers part of its security sphere.
The proposed mission is being promoted primarily by France and Britain. Plans under discussion include warships, mine-countermeasure vessels and aerial surveillance capabilities designed to protect commercial traffic and reassure shipping companies.
European forces could initially remain in the Gulf of Oman rather than immediately entering the Strait of Hormuz. Such an arrangement would allow them to prepare for escort, surveillance or mine-clearing duties without provoking a direct confrontation with Iran.
Tehran has repeatedly opposed a foreign military presence in the waterway, maintaining that regional states—particularly Iran and Oman—should be responsible for its security.
For Berlin, the success of the US–Iran agreement is therefore central to deciding whether a European mission is necessary, acceptable and legally defensible.
Germany’s hesitation does not mean that it opposes European involvement altogether. The government has stressed the importance of unrestricted navigation and the restoration of normal commercial traffic through the strait.
The waterway connects the Persian Gulf with the Gulf of Oman and is a crucial route for global oil and liquefied natural gas exports. Prolonged disruption has raised transport and insurance costs while contributing to volatility in international energy markets.
Berlin nevertheless wants clarity about the mission’s objectives, rules of engagement and international legal basis before offering ships, personnel or other military assets.
Poland has expressed a similarly cautious view. Warsaw and Berlin have both suggested that the European Union’s existing naval operation, Aspides, could provide a possible foundation for action in the Persian Gulf.
Aspides was established in 2024 as a defensive mission to protect commercial vessels from attacks in and around the Red Sea. Its current responsibilities include safeguarding freedom of navigation and monitoring maritime conditions across a wider area that includes the Gulf of Oman and the Strait of Hormuz.
Using Aspides would provide an established European command structure and allow participating countries to share some operational costs. It could also avoid the need to construct an entirely new mission from the beginning.
However, significantly expanding the operation’s duties would require political agreement among all 27 EU member states.
That consensus may prove difficult. Several European governments remain concerned that deploying naval forces too quickly could draw the EU into a conflict led by the United States and Israel or undermine diplomatic efforts to stabilise relations with Iran.
Earlier in the crisis, Germany was sceptical about broadening Aspides beyond its Red Sea role. German Foreign Minister Johann Wadephul questioned whether an operation that had struggled to eliminate threats to shipping in its existing area could deliver better results in the far more sensitive Strait of Hormuz.
The latest diplomatic developments have changed the context but not eliminated those concerns.
The preliminary US–Iran accord reportedly provides for an end to hostilities, the lifting of the American naval blockade and the restoration of shipping through Hormuz. It also opens a limited negotiating period in which the two sides are expected to address nuclear restrictions, sanctions and wider security arrangements.
Yet the sequence of those steps remains disputed. Both parties may retain the ability to withdraw if the other fails to fulfil its commitments, making European governments reluctant to base a military decision on an agreement that could still unravel.
Germany is also likely to examine whether Iran has accepted any international role in supervising or securing the strait. A European operation deployed without Tehran’s consent could face harassment or be interpreted as an attempt to restrict Iranian sovereignty.
France and Britain argue that a carefully defined defensive mission could reassure shipping companies and accelerate the return of commercial traffic. Even after a political agreement, carriers may be hesitant to resume normal operations while the threat of mines, drones or renewed hostilities remains.
The European debate therefore concerns more than whether ships should be sent. Governments must determine whether the mission would escort vessels, clear mines, conduct surveillance or merely remain nearby as a deterrent.
Each option carries different military requirements and legal risks.
For Germany, a written and credible US–Iran settlement would provide the political foundation needed to make those decisions. Without it, Berlin appears unwilling to commit forces to a mission whose purpose could be overtaken by diplomacy—or whose presence could undermine it.
The approach reflects Germany’s broader preference for linking military involvement to a clearly defined mandate, international legitimacy and realistic objectives.
Berlin supports the restoration of secure navigation through Hormuz, but it is not prepared to treat naval deployment as an automatic response.
Germany’s message is that European ships may eventually have a role in stabilising the waterway. Before making that commitment, however, it wants to know precisely what peace Washington and Tehran have agreed—and whether a foreign fleet would help preserve it.
