The universal is "the other", "the danger", "the challenge."

The unity of the destiny symbolises the belief that "the people are one" and propelled (destiny) to confront the universal and conquer it. It emphasises exceptionalism too.

Admittedly, you can put non-fascist interpretations to these concepts, but it does seem to me to fit well with Franco and other famous fascists. At the same time you can see the psychological parallels with people like the Bush administration in this attitude.
