When American and Israeli forces struck Iranian military sites in March 2026, most European leaders issued cautious statements and moved on. Spain’s Prime Minister Pedro Sánchez took a riskier stand. He declared “No to war,” closed Spain’s airspace to U.S. military aircraft, denied the United States access to the Rota naval base and Morón air base, recalled diplomats, and made Spain the loudest European voice opposing the ongoing operation in Iran—which Sánchez calls “an illegal, absurd and cruel war.”
These diplomatic decisions came with concrete backing. Official statistics from Spain’s Secretary of State for Trade show that Sánchez’s government approved $1.54 million in dual-use exports to Iran during 2024 and the first half of 2025. The shipments included detonators, explosives of types A, B, and E, chemical reagents, control software, and high-precision machine tools such as computer numerical control lathes, milling machines, and machining centers. Nearly 70 percent of these items went to state-linked or public Iranian companies. Almost the entire $1.54 million value consisted of category two machine tools designed for precision manufacturing in missile and drone production.
In March 2026, Ambassador Reza Zabib declared from Madrid that Iran could strike any American base in Europe and explicitly named the Rota and Morón facilities.
The pattern runs deeper and longer. Since Sánchez took office in 2018, Spain has authorized roughly $7 million in dual-use technologies with military and nuclear-adjacent applications for Tehran. In 2024 alone, machinery exports topped $80 million. That year, Spain also shipped $27.5 million in industrial furnaces and $16.4 million in valves, equipment that Iran’s defense sector can readily repurpose. Total Spanish defense-related exports to Iran reached $198.72 million.
Iran returns the favor by explicitly carrying out an anti-Western “crusade” from Spanish soil. The embassy in Madrid currently hosts military and intelligence attachés. In March 2026, Ambassador Reza Zabib declared from Madrid that Iran could strike any American base in Europe and explicitly named the Rota and Morón facilities.
The strategic fallout is immediate and measurable. Spanish components now feed the production lines that build the ballistic missiles and drones Iran fires at the State of Israel and American troops in the Middle East. Iranian state media thanked Spain by pasting anti-war quotes made by Sánchez onto its missiles as propaganda trophies. A member of the North Atlantic Treaty Organization (NATO) that hosts critical American bases has instead supplied technology to the adversary while refusing to support allied strikes against it.
The geostrategic stakes could not be higher. The Rota naval station sits astride the Strait of Gibraltar, controlling vital sea lanes between the Atlantic and the Mediterranean. It supports U.S. naval operations across three continents and hosts forward-deployed assets essential for rapid response in the Middle East and North Africa. Morón functions as a key air logistics hub for tanker aircraft, cargo lifts, and special operations staging. Together these bases enable the power projection that underpins NATO deterrence and American commitments to European security. By denying their use, Spain forced the United States to reroute aircraft and exposed a fracture in alliance cohesion at the precise moment Iran tested its missile swarms against Israeli defenses.
The steady supply of precision machine tools and dual-use parts gives Tehran’s military-industrial complex room to breathe.
For Iran, Spain has become a sanctions-resistant lifeline inside Europe. The steady supply of precision machine tools and dual-use parts gives Tehran’s military-industrial complex room to breathe. Iranian engineers use this equipment to refine guidance systems, warhead casings, and propulsion components for the very missiles and drones that now threaten stability across the region. The diplomatic cover that comes with Spanish criticism further signals to Tehran that the West remains divided and exploitable.
Spain’s policy also highlights a broader European vulnerability. While partners debated proportionate responses and collective defense, Spanish trade with Iran continued without interruption. The $1.54 million in sensitive exports during 2024 and early 2025 alone provided Iran with manufacturing capacity it cannot source elsewhere under sanctions. This commercial engagement, combined with public opposition to allied operations, creates a permissive environment that Iran exploits to erode Western unity.
Spain, a NATO ally of 48 million European citizens, chose cheap commerce and domestic applause over alliance discipline and collective security. It kept the pipelines open and helped sustain a regime that openly threatens America and Western interests in general. The choice is stark: keep feeding Iran and dividing the West or finally act like a serious ally in an age of precision warfare and hard power.
