It sure seems like the Russians are just attacking any liberal leader, mounting extensive influence operations to get the ordinary people of their countries to hate them and want to get rid of them (and often to replace them with monsters, if any particular monsters are available).
I have not the first idea at all about Carney, I just know Trudeau. He seemed fine. I also have no particular evidence about the Russians being the ones who are doing all this, but the pattern of liberal leaders having all these wild uprisings against them which gets rid of them in the end seems absolutely unmistakable. And little pieces of the uprisings definitely show a consistent pattern of Russian influence, always in precisely the same direction, when little indications show through the cracks.
And, it definitely seems like a significant problem.
