I find that those countries which boast superficial national pride, jingoism and suchlike in reality have very little to be proud of. Those places which have actually succeeded in creating vibrant economies and harmonious society are often modest and unassuming with little fanfare. Flag waving and over or inappropriate use of the national anthem seems like plastic ceremony with no real purpose.
What the people need is focus, a common goal and a leadership who instill confidence and encourage excellence in every person regardless of their background.... unity through ambition!
