I remembered this old cartoon from before WWII that talked of men fighting until they all where dead. So while we most likely couldn't with 1920's/30's technology make our self extinct, make the situation in 1940 similar to the one shown in cartoon (Not the happy furry talking animals, but the wars having killed of great amounts of people)
