"You and the Naboo form a symbiont circle. What happens to one of you will affect the other. You must understand this."
First off, no brother wars. The plight of the average Canadian being sabotaged by sociopathic elites and self-interested boomers is sad, not funny, and most of us can relate to it in some way. Any western nation being conquered is a terrible waste. We can only hope that they will find a way to deal with this problem.
Two, it may be 'easier' to conquer, but having a colony of parasites slavering at the mouth of your northern border is bad, no matter what. After all, you're giving America a pass on its brownification because of its southern border; now you'll just have two in that state. Remember that Canada was a good ally before TDS took over, and it could be so again.
