Here are some pointers from the Nationalist movement in Argentina. This is distinct from the Peronist movement which I prefer. But there are some real pointers here for National Revolutionaries to build a Movement that can take on not just the Left but the government as well.
Nationalism: Anti-democratic political movement.
Nationalists created influential school of history known as Revisionism: Create blueprints for the future through a mythic re-interpretation of the past.
Organic movement opposed to pluralist parties.
Nationalist movement had influence on revolutionary left: Its myths & icons, ideological outlook, propaganda techniques.
New Left of the 1970s inherited cult of authoritarian leadership from Nationalists; copied their attempt to create a radical counterculture that used historical invention, xenophobia & conspiracy theories.
Left’s brand of anti-imperialism denounced anti-national machinations of international monopoly capitalism: Had roots in onslaughts of the Nationalists against Jewish or Masonic conspiracies inspired from abroad.
Nationalist movement never more than a fraction of the population and divided into several groups.
Often formed militia-style organizations but more important as dissident intellectuals. Influence stemmed from doctrines and links to power groups in the military.
“Right” misleading term as Nationalists were outside the formal political system. Like Primo de Rivera and the Falange: Nationalists not a party but a movement.
Almost an anti-party: Belongs to neither Left nor Right.
