Socialists = Fascists = 90% Communists
Mussolini was a totalitarian statist, just like Mao, Hitler and Stalin.
I except Franco as he doesn't seem to 'fit'. He appears to have seized power simply to keep the communists out, and didn't come in on Hitler's side in the war.
That makes sense. I remember when Franco died he made sure the King was restored to power. And then the King did the right thing and turned power over to a democratic government.
