Andy Rooney said this quote

One question in my mind, which I hardly dare mention in public, is whether patriotism has, overall, been a force for good or evil in the world. Patriotism is rampant in war and there are some good things about it. Just as self-respect and pride bring out the best in an individual, pride in family, pride in teammates, pride in hometown bring out the best in groups of people. War brings out the kind of pride in country that encourages its citizens in the direction of excellence and it encourages them to be ready to die for it. At no time do people work so well together to achieve the same goal as they do in wartime. Maybe that's enough to make patriotism eligible to be considered a virtue. If only I could get out of my mind the most patriotic people who ever lived, the Nazi Germans.
