A patriot can see faults in what their country does, as everybody and every organization of bodies makes mistakes. A patriot seeks atonement for those mistakes, to make things right, and come back stronger, with more support from the world.

It seems you're confusing patriotism with jingoism: "we're the greatest country in the world, we never make mistakes, so we don't need to learn from them, suck it victims, everyone is in a grand conspiracy against us because they're jealous", etc, that sort of thing. That's how you get the sort of "patriots" that one could find in 1939 Germany. I guess some people want that.
