The arguments for leaving NATO that Spain's government refuses to hear

Spain's entry into NATO, Sánchez's stance toward Trump and historical pressures have reignited the debate over remaining in the Alliance.

Why some sectors are calling for Spain to leave NATO

Spain joined NATO in 1982 through an organic law, not a referendum, and the 1986 plebiscite only ratified the conditions of membership. This debate, which resurfaces with every Atlantic crisis, has gained momentum trinc Pedro Sánchez's clash with the Trump administration and his refusal to allow military stopovers at Rota and Morón.

The referendum that was never binding

The official narrative holds that Spaniards freely voted to join the Alliance. However, several historical sources suggest that the 1986 referendum was framed as a binary choice between "staying with limitations" or "becoming a full member" — with no option to leave. There is also mention of pressure from the United States, including a threat to invade the Canary Islands if Spain did not join, as claimed by former minister Fernando Morán.

Sánchez's turn amid the transatlantic crisis

After Europe was excluded from the negotiations on Ukraine and Trump's tariff escalation, Sánchez adopted a profile of explicit opposition. He vetoed the use of Spanish bases for US operations in the Middle East and aligned himself with other European leaders demanding autonomous defense. This move, though applauded by part of public opinion, has been dismissed as posturing by those who recall that the same Sánchez supported NATO's bombing of the Balkans during his formative political years.

The proposal for a European military alliance

Supporters of leaving argue that NATO is an obsolete organization that serves the geopolitical interests of the United States, not European security. They propose creating a continental defense pact with its own structure and genuine autonomy. The main objection, however, is the cost: building an independent military system would require massive investments in a context of budget constraints and public debt.

As of this debate, no major party has included leaving NATO in its program, but discontent is growing. Voting discipline in the European Parliament and logistical dependence on US bases act as a brake. Meanwhile, the question remains open: is it worth continuing to pay the political and economic price of the Alliance?
