The bond of unity of most nations is the idea that they are one family, a family of common lineage usually speaking a common language and adhering to a common religion. Sometimes this is cemented by having a hereditary monarch as a symbolic national father or mother.
We US Americans lack a common lineage. We consist of all kinds of people—descendants of the original white Anglo-Saxon Protestants, African slaves, native American peoples and Spanish-speakers acquired by conquest, plus immigrants from literally every continent in the world.
So maybe we need an American creed, or an American myth, to bind us together.
But wait a minute! Canada, our good (and often better) neighbor does all right, without any obvious sense of Canadian exceptionalism. How do they do it?
A Canadian friend of mine summed up her idea of her nation this way:
Canadians suffer from boredom and blandness. Even the most conservative politician in Canada believes in universal health care run by the government.
There were some differences here concerning the role of the private sector in healthcare, but in general those differences were worked out years ago. Canadians put up with high taxes. Doctors are basically civil servants.
What myth warms our hearts? Fairness and multiculturalism?
Refugees and immigrants in Canada are enjoyed. Their story adds a little spice to the Canadian meat and potatoes. They are not pushed to become CANADIANS. What would that even be? It would be very unusual in Toronto to walk down the street for one block and not hear 3 or 4 languages spoken.
One very common problem is people in their 40s who have parents who came to Canada 30 years ago and never learned English. I know a lot of people in that situation, who feel an obligation to be their parents’ interpreters at a moment’s notice (even though they have demanding careers and young children to raise).
There are no illusions that Canada is the leader of the Free World, no sense that we are shining beacons on a hill, no sense that we set the world’s agenda. We try to do our fair share of the world’s peacekeeping.
This makes Canadians a bit like children. We put the government in charge and then complain mightily about everything they do.
What made the USA and Canada different?
The USA had to fight for its independence. Canada never had to. The leaders of the USA in 1776 were mostly descendants of the original British settlers, but they had to figure out a rationale for independence not based on lineage.
The rationale was that we US Americans stood for the right to life, liberty and the pursuit of happiness.
