How Was Monroe's Statement in His First Inaugural Address That

How was Monroe's statement in his first inaugural address that "no country was ever happier with respect to its domain" contradicted by subsequent events?

A) If the U.S. was happy with respect to its domain, it would not have to expand to obtain Florida or more land in the West.
B) If the U.S. was happy with respect to its domain, it would not have changed to a market economy and begun industrialization outside of the home.
C) If the Great Lakes and the great rivers were important to the U.S., it would not have built national roads.
D) The Great Lakes and great rivers ended up being of little value to the U.S. during the early nineteenth century, causing the U.S. to seek more "domain."
E) Because of poor relations with Native American tribes in the Great Lakes and great rivers regions, the U.S. wasn't truly happy with respect to its domain.
