The article discusses the historical context of Spain's entry into NATO, which ended the country's international isolation after years under a dictatorship. Initially, the PSOE under Felipe González capitalized on an anti-militarist stance during the 1982 election campaign, promising a binding referendum on Spain's NATO membership. Their slogan 'NATO, not at any price' was designed to appeal to voters who were skeptical of military alliances.

However, following their electoral victory, the PSOE underwent a pivotal transformation regarding NATO. González's administration launched a vigorous persuasion campaign that reframed NATO from an imperialistic entity to a modern and European-oriented alliance. This transition, occurring within just four years, was a dramatic shift in political strategy, reflecting a larger trend towards integration with Western institutions after the Franco regime.

The implications of this historical pivot are being examined now in light of contemporary controversies surrounding NATO and the U.S. under President Trump. The article draws parallels between past and present sentiments regarding military alignment and national identity, indicating ongoing debates about Spain's role in NATO and how it informs the country's political discourse today.
