The Nationalist movement in Argentina was distinct from the Peronist movement. Peronism (Justicialismo) was based on the working class, initially in alliance with the military. Whereas, the Nationalists had their base in the middle and upper-middle class. There was some overlapping, but the Nationalists broke with Peron at the end of his first term.
In Argentina, Nationalism was an anti-democratic political movement. They were an organic movement opposed to the pluralist political parties.
Tactically, the Nationalists created an influential school of history known as revisionism. By this, they created blueprints for the future through a mythic reinterpretation of the past.
The Nationalist movement had influence on their enemies of the revolutionary left: its myths & icons, ideological outlook, propaganda techniques.
From the Nationalists, the New Left of the 1970s inherited the cult of authoritarian leadership; copied their attempt to create a radical counter-culture that used historical invention, xenophobia and conspiracy theories.
The Left’s brand of anti-imperialism denounced the anti-national machinations of international monopoly capitalism. This had roots in the onslaughts of the Nationalists against Jewish or Masonic conspiracies inspired from abroad. (Most Nationalists at least paid lip service to Catholic Traditionalism.)
The Nationalist movement was never more than a fraction of the population and was divided into several groups. The best known group was Tacuara (officially Movimiento Nacionalista Revolucionario Tacuara).
The Nationalists often formed militia-style organizations but were more important as dissident intellectuals. Their influence stemmed from their doctrines plus links to power groups in the military.
“Right” was a misleading term to refer to them as the Nationalists operated outside the formal political system.
The Nationalist movement was heavily influenced by the original Spanish Falange (Falange Espanola de las Juntas de Ofensiva Nacional-Sinicalista) of Jose Antonio Primo De Rivera and Ramiro Ledesma Ramos. Like the Falange, not a party but a movement; almost an anti-party belonging to neither Left nor Right. And like the Falange, they were serious. (In Spain, the orginal JONS newspaper was entitled “The Conquest of the State”).
Lessons to be drawn:
1) Stay clear of Establishment-sanctioned ‘liberals’ & ‘conservatives.’
2) Ideological coherence.
4) Ties to power groups in the military.
