The US declared war on Britain (which didn’t want to fight the war), tried to seize Canada, failed, and then spent most of the rest of the war mostly on their own territory trying to fend off the vengeful blows from the British before a treaty returning to the status quo ante bellum (which is what the British wanted all along).
How is that an American victory? How is it even a draw?
The Brits did not respect US independence. A war was inevitable. The final decisive US victory at New Orleans earned the US respect and British acceptance of the Louisiana Purchase. If the British had captured New Orleans, the outcome could have been very different.
The British wanted us to have Maine?
“How is that an American victory? How is it even a draw?”
Because we get to live here, and British people have to live there. We won.
