Yeah so this is mostly just a difference of definition. When I say extinction I mean what you describe, essentially a total collapse of modern society. I don't care whether/how long a few people survive somewhere, your scenario is apocalyptic enough for me to label it an apocalypse.

I also think this process is likely to trigger a new world war. When nations start collapsing there will be two possible outcomes - other nations take them in or they go to war. They won't just sit down and die. And everyone else won't be able to handle the number of refugees even if they want to.
