Trump Threatens Spain With Trade War Over Iran Base Refusal

A NATO Ally Draws a Red Line

The diplomatic relationship between the United States and Spain fractured sharply this week after Madrid refused to allow Washington to use jointly operated military bases on Spanish soil to support strikes against Iran — and President Donald Trump responded by threatening to cut off all trade with one of America's oldest European partners.

The flashpoint came over the weekend when Spanish Foreign Minister José Manuel Albares announced that bases at Rota and Morón in southern Spain — key US military installations operating under a bilateral agreement — would not be made available for the Iran offensive. "Spanish bases are not being used for this operation, and they will not be used for anything not included in the agreement with the United States, or for anything that is not in accordance with the Charter of the United Nations," Albares stated plainly, according to Al Jazeera.

Flight tracking data confirmed the fallout: 15 US aircraft, including refuelling tankers, quietly departed the two Andalusian bases shortly after Madrid's declaration. Within days, the dispute escalated from military logistics into an all-out economic confrontation.

Trump's Sweeping Trade Threat

Speaking from the Oval Office during a meeting with German Chancellor Friedrich Merz, Trump announced he had directed Treasury Secretary Scott Bessent to "cut off all dealings with Spain." He called Spain "unfriendly" and compounded the attack by renewing criticism of Madrid's failure to meet NATO's 5% of GDP defense spending target, according to Bloomberg.

The economic stakes are significant. The US ran a trade surplus with Spain of $4.8 billion in 2025 — exporting $26.1 billion in goods while importing $21.3 billion — meaning any trade embargo would hurt American exporters as much as Spanish ones. Spain's goods exports to the US total around 16 billion euros, roughly 1% of Spain's GDP, making America its sixth-largest export market, per Fox Business.

Sánchez Stands Firm

Spanish Prime Minister Pedro Sánchez did not blink. In a forceful speech, he described the US-Israeli strikes on Iran as a "disaster" and offered one of the most pointed rebuttals from a NATO ally since Trump's return to power.

"We will not be complicit in something that is bad for the world and contrary to our values and interests simply out of fear of reprisals from someone. It's naive to believe that democracy or respect among nations can spring from ruins."

The Spanish government said it had "the necessary resources to contain the possible impact of the trade embargo," and insisted any US action must respect "the autonomy of private companies, international law and bilateral agreements between the European Union and the US," according to CNBC.

Wider NATO Fractures

Spain is not alone. Trump also criticized the UK's Keir Starmer for a lukewarm response to the Iran campaign. The episode lays bare a deeper fissure within the Western alliance: several European NATO members have refused to endorse the US-Israeli military campaign, citing international law and fears of wider regional escalation.

Analysts note that a full trade embargo on Spain — a G20 economy and major EU member — would be legally complicated under existing EU-US trade frameworks and WTO rules, making Trump's threat partly rhetorical. Still, the standoff signals a potentially lasting shift in US-European relations as the Iran conflict reshapes alliance politics in real time.

What Comes Next

With hostilities in Iran still ongoing, both sides face pressure. Spain must balance its sovereignty and public opposition to the war against its deep economic and security ties with Washington. For Trump, cutting off a NATO partner that provides irreplaceable Atlantic basing infrastructure carries its own strategic costs — regardless of the political optics at home.
