Minor nitpick: can you even call that “jingoistic”?

I'm specifically thinking of the "I'm from Buenos Aires" quote when I call it such, as that is a great example of the particular patriotic fever that would define it. I know the Left and Boomers have turned it into a dirty, negative word but I think that's a perfect example of it becoming a completely justified and likely the best course of action.

Also the very specific problem with the movie where their propaganda and superiority complex consistently leads them to underestimating their opponents and getting untold number of their own people killed. While the director was trying to make a "Nazis/Americans dumb" political message, I think we can see the greater philosophical issue of believing your own hype too much that it blinds you, which is where extreme patriotism can be an issue.
