Canada will be invaded by a UFO army from Nazi colonies inside Hollow Earth and on the Moon, led by a bio-android mecha-suit Adolf Hitler.
This will occur because the North Pole, or opening to hollow earth, is closest to Canada. It's impossible for the Canadian or American Army to stop Hitler's Nazi UFO army.
The Nazis will choose Canada because there's a large Asian and Middle Eastern population that understands their own religious and philosophical teachings that can be embraced by white people (to ultimately destroy the international capitalist evil elites of society)
The future Canadian Nazis will organize Muslims, Hindus, Taoists, etc. into an entirely new version of multiculturalism that does not result in conflict and chaos, but rather order, under a global National Socialist Empire
