Because the US was there.
I am talking about if America didn’t exist. We were protecting Canada from the USSR.
You don’t think that the USSR, who wanted to spread communism all over the world, would have left free Canada alone if America never existed?
I don’t think they would. It doesn’t fit with Stalin’s world conquest.
Of course, without the US, Canada might have been stronger, especially if they held America’s recourses, but then we are getting into a bunch of What-ifs.
