Or it could be said that WE lost no territory.
We took on the most powerful army in the world and fought to a draw.
That's a big win
I measure our performance in the War of 1812 against our accomplishment of our objectives vis-a-vis English accomplishment of THEIR objectives. We had certain goals in mind when declared war in the first place. We achieved exactly ZERO of those goals. The British accomplished all of their objectives.
That's a pretty solid win in my book.
