American is a virtue, it is not a nationality.
While that concept has an attractive universalist value, please allow a foreigner to quietly disagree with you.
In practice, people are not the same from one country to another. They don't even particularly long for these "universal" ideals of democracy, freedom and happiness.
I believe that people are the product of the environment in which they live in.
You're very rarely born somewhere out of chance.
By thinking that being an American is a virtue and not a nationality, you are thinking the way people in France and England did when they decided to create colonial empires. IMHO (I'm not trying to be aggressive), you are also being somewhat unrespectful of the sacrifices that so many people had to make in order to build the US of A.
Regarding the French colonial empire, it has to be said that while the primary interest was financial, there really was a desire to export our values which we thought were to be naturally adopted by everyone.
