Between the world wars, there were American contingency plans for war with the British empire, War Plan Red.

The plan proposed a US victory by conquering Canada and British Caribbean possessions forcing Britain to sue for peace.

The plan contemplated that captured Canada would be annexed to the United States.*

But how plausible is this? Assuming we get to this point (UK and US actually go to war and Canada is lost), how will American occupation of the former dominion go?

There will be resistance as Canadian national identity has been based on preventing domination or annexation by the US. This isn't going to go away, being occupied probably will strengthen it. I don't think it is an easy annexation, one way or another.

However, after such a military defeat, the UK will be gone and not come back, one way another, Canada has left the British Empire.**

So what will be the outcome of this scenario?

- New American States?
- New American Territories?
- A Canadian republic?
- A patchwork of all of the above?

**In a US v UK 1920's/30's war there is also the possibility that Canada will declare neutrality and effectively leave the British empire anyway.
