It's a historic quirk that the US is a single country. It hardly feels like one most days.
It is not a surprise that region can't find anyone else (in the rest of the economic zone over which it claims dominion) willing to die for its interests, especially when their interests have been revealed to be nothing but "loot the rest of the nation".
Toronto/Ottawa/Montreal, demonstrably, cannot do that.
Which of the two strategies do you think give the cities a greater chance of survival?
canadian: no, you're the historical quirk!
native american: you're both historical twerps.
