It would mean that whatever the US might hope to gain from invading Canada would be dwarfed by what the US would lose in the conflict.
The problem is this is already the case. Nuclear weapons may make it even more lopsided, but the country is already losing more than it stands to gain from an invasion purely on the economic results.
Something I’ve been thinking a lot lately is that democracy is a process. It is a means by which we attempt to ensure a just and fair government for all. It’s not an end in itself; we don’t want democracy because democracy, at least not once people really think about it.
Which leads me to a saying. “The ends do not justify the means.” This is a commonly held statement. However, it also works the other way:
The means do not justify the ends.
That means it doesn’t matter if something was done by the rules, using the process, it doesn’t matter if we voted for it, it doesn’t matter what process was used to achieve it. If the ends are wrong, going “well, it’s what was decided democratically” isn’t an excuse.
If one person or a few people have a definition wrong, that’s a thing that can be corrected.
If the majority of people think that’s the definition, and it’s been that way for decades, then you have the definition wrong.
There certainly wouldn’t be any regrets (because you would not have time to do so before death).
