Despite pressure from US President Donald Trump for European allies to join the war against Iran, or at a minimum provide bases and airspace access, most European capitals have taken a firm stance: this is not their war. Governments across Berlin, Paris, Madrid, and London have refused direct involvement, limiting their response to calls for de-escalation and condemnation of violence.
This unified position reflects more than temporary hesitation. Europe’s refusal is rooted in a complex framework of legal, military, economic, and political constraints that make participation both costly and strategically unnecessary.
Legal and Institutional Constraints
At the core of Europe’s position lies the legal framework governing NATO. Article 5 applies only to collective defence in response to an armed attack against a member state within Europe or North America. A US-led offensive against Iran does not trigger this clause, nor does it legally bind allies to participate.
Additionally, the use of European bases and airspace is subject to national sovereignty and parliamentary oversight. Spain has closed its airspace to US aircraft targeting Iran, while Italy has restricted access to key military bases without prior approval. France has also refused the transit of weapons shipments, reinforcing its independent security decision-making.
This distinction between defensive obligations and offensive operations limits Europe’s ability to support US military actions beyond NATO’s defined scope.
Military Priorities and Security Risks
European security priorities remain focused on deterring Russia and reinforcing the eastern flank, particularly in light of ongoing tensions in Ukraine. Engaging in a distant conflict in the Gulf risks overstretching military resources and weakening core defence capabilities.
There is also growing concern over the depletion of critical defence systems. US missile stockpiles, including advanced interception systems, have been significantly reduced during the war, and Europe relies heavily on these systems for its own security and to support Ukraine. Opening a new front would intensify this strain.
Moreover, escalation with Iran raises the risk of retaliatory actions against European assets in the Middle East or Mediterranean. European security agencies warn of potential cyberattacks and proxy operations, making direct involvement a high-risk decision.
Economic Pressures and Energy Vulnerability
The conflict has already triggered significant disruption in global energy markets. Partial closure of the Strait of Hormuz has driven sharp increases in oil and gas prices, with European gas prices rising by over 70 percent since the escalation began.
This comes at a time when Europe’s economy is already under pressure. Rising energy costs threaten to slow economic growth and push inflation higher, increasing the risk of stagflation. Countries like Germany have already experienced rising fuel costs, with broader implications across industries.
Europe remains heavily dependent on imported energy, and disruptions in supply chains could lead to shortages in aviation fuel and diesel, affecting transport, trade, and tourism. These risks make further escalation economically unsustainable for European governments.
Political Realities and Public Opposition
Public opinion across Europe is strongly opposed to the war. Surveys indicate that a majority of citizens in the United Kingdom, Spain, and Germany reject involvement, reflecting widespread war fatigue following previous interventions in Iraq, Libya, and Afghanistan.
This domestic pressure has translated into political caution. Governments are unwilling to risk electoral backlash by entering an unpopular conflict. Even some political factions that previously aligned with Trump have shifted their position and criticised the war.
At the same time, European leaders are wary of appearing subordinate to US or Israeli decision-making. Officials have emphasised the importance of strategic autonomy, noting that they were neither consulted nor presented with a clear roadmap for the war.
Strategic Neutrality as the Rational Outcome
Taken together, these factors explain why European neutrality has emerged as the most logical course of action. Rather than engaging in a high-risk offensive conflict, European states are prioritising stability, economic resilience, and defensive commitments within NATO’s framework.
This position allows them to maintain alliances while avoiding entanglement in a war that does not align with their legal obligations, strategic interests, or domestic priorities.
