Oh yeah something I forgot to mention was the rebirth/palingenesis being its motivating and unifying Sorelian myth. This as a concept is one of the most important things that distinguishes fascism from bourgeois nationalism, reaction etc.

I'd revise it as:

"The Third Position (fascism) is revolutionary nationalism rooted in an organic worldview with the unifying Sorelian myth of national rebirth also known a palingenesis. It is built on social capital and is a grassroots populist struggle of the people against the forces of International Finance (the ruling elite) and the spiritual decadence of Materialism (the ideologies of Liberalism and Marxism)."
