I don't think you have any idea how big the United States is. The United states is basically the exact same size as the entire *continent* of Europe.
Europe - Area:
10,180,000 km2
United States - Area:
9,826,675 km2

Geographically speaking yes, but what good is that as a statistic?
Europe has over TWICE the population of the United States.
