European Union leaders have rejected calls to join military operations in the Strait of Hormuz, emphasizing legal limitations, economic risks and policy considerations as tensions linked to the war involving Iran continue to disrupt global energy markets.
The issue emerged during a meeting of EU foreign ministers in Brussels on Monday, where officials discussed the impact of the conflict on international trade routes and oil prices. The strategic waterway has become a focal point of geopolitical tension after the United States and Israel launched attacks across Iran earlier this year, prompting retaliatory missile and drone strikes from Tehran across the wider Middle East.
United States President Donald Trump has urged NATO allies to support a naval coalition to secure the Strait of Hormuz and ensure freedom of navigation for commercial vessels. However, several European governments have pushed back against the proposal, indicating that they do not intend to participate in military operations linked to the conflict.
German Foreign Minister Johann Wadephul stated that Germany does not plan to join combat activities in the region. Speaking ahead of the EU meeting, he said European governments expect greater consultation and transparency from the United States and Israel regarding the objectives and outcomes of their military actions before considering future security arrangements in the Gulf region.
European officials have highlighted legal and policy concerns regarding potential involvement. NATO’s founding treaty primarily commits members to collective defence if one member is attacked, and European leaders have indicated that the current conflict does not fall within those obligations. As a result, policymakers argue that participation in combat operations could raise questions under international law and alliance frameworks.
German Defence Minister Boris Pistorius also questioned the strategic value of sending a small number of European naval vessels to the area when the United States Navy already maintains a significant military presence in the region. He stressed that the conflict was not initiated by European countries and therefore should not automatically involve them in military engagement.
The dispute is unfolding amid growing concerns about the economic impact of disruptions in the Strait of Hormuz. The narrow maritime corridor connects the Persian Gulf with global shipping routes and handles roughly one-fifth of the world’s oil shipments. Any prolonged disruption to navigation in the strait can have major consequences for global energy supplies and international trade.
Following the escalation of hostilities, tanker movements through the waterway have declined sharply, and global oil prices have surged above 100 dollars per barrel. Energy analysts warn that continued instability could increase transportation costs, fuel inflation and create uncertainty in global supply chains, particularly for countries dependent on Middle Eastern energy exports.
European policymakers therefore face a complex trade and policy challenge. While the EU strongly supports freedom of navigation under international maritime law, leaders are cautious about actions that could deepen the conflict or place European forces directly in a war zone.
EU foreign policy chief Kaja Kallas said member states must first assess what role they are willing to play in restoring navigation through the strait. She acknowledged that reopening the route is critical for global markets but indicated that the bloc must consider diplomatic and policy options before any operational decisions are made.
One policy proposal under discussion involves expanding the EU’s maritime security mission known as Operation Aspides. The mission was established in 2024 to protect commercial vessels from attacks in the Red Sea. Some European governments have suggested that the operation could potentially be extended to support maritime security efforts in the Gulf.
However, support for expanding the mission remains limited. Greece has stated it will not participate in military operations in the Strait of Hormuz, while Italy has confirmed it is not currently involved in naval deployments that could be extended to the region.
Denmark’s foreign minister Lars Lokke Rasmussen said European governments should remain open to discussions on protecting maritime trade routes but stressed that any policy response should focus on de-escalation rather than expanding military conflict.
The United Kingdom has indicated that it is working with partners on a broader strategy to restore freedom of navigation in the Middle East. Officials have acknowledged, however, that reopening the strait will be difficult while the conflict continues.
European leaders are also concerned about wider geopolitical consequences. EU officials noted that rising oil prices could benefit Russia’s war economy, as Moscow relies heavily on energy revenues to fund its military operations in Ukraine.
The debate highlights the broader intersection of law, trade and foreign policy as governments attempt to respond to one of the most sensitive maritime crises in recent years. For European policymakers, the challenge is balancing the need to protect global trade routes with adherence to international legal frameworks and the strategic goal of preventing further escalation in the Middle East.
