It was many years ago I studied the Spanish Civil War. If you’re interested, the standard work then was by Hugh Thomas, ‘The Spanish Civil War’ (a huge work). The standard work on Spanish fascism and Jose de Rivera then was ‘The Falange’ by Taylor.
I read the Thomas work last year. McGee, pick up it sometime.
The big difference is that Spain in the 1930’s was a proxy war between Germany and the USSR. We don’t (yet anyway) have the same situation.
