Question

How did the War of 1812 help establish the reputation of the United States in international affairs?

Answer 1

The United States eventually won the war. This showed other countries that even in the worst situations the country could hold it's own.

Answer 2

It showed that the U.S. was a nation hunting for heads, it was a war over Canada, fought by the British and the U.S., and ultimately hurt us. We lost that war (according to some, it was a stalemate), and (if I'm not mistaken) the white house was burned down.
