we've gone from sleeping with the elephant to punching the elephant in the trunk. it's not smart.
the idea of two independent countries on this continent is likely unsustainable, in the long run, and the question is not whether we integrate, but how we do it. in the long run of history, neither canada nor the united states are nation states. these are both transient entities to advance british colonialism, and neither will have long histories or distinct cultures that are entered into the annals of history. future historians may talk of the period where the british colonies were divided by in-fighting, and they may even describe how the british empire moved it's capital from london to washington, as it was swallowed by it's more powerful colony.
to the extent that there are differences between the north and south of the british colonial project, they are better addressed via different political parties, and not through the folly of false nationalism or through the stupidity of civil war. i'm not about to die for the profits of the bourgeoisie.
only the chinese benefit from dividing and conquering the british colonies.
