[League of Extraordinary Gentlemen Comic] How has the world lasted so long?

In the League universe all fiction is true, if that is the case then how has is humanity still alive with all the nuclear wars, various fictional wars, zombie apocalypses, alien attacks dating from the Victorian era (The War of the Worlds part of the comic) and various universe destroying threats, how hasn’t the planet been destroyed several times over?

"All of popular fiction is present" but there's definitely changes made to famous fictional works in this universe. For example, while "Jimmy Bond" is real, the James Bond story "Doctor No" is revealed to have been a hoax. The government from 1984 happened in 1948 and fell pretty quickly. So a world-ending story may happen to some extent in this universe, but dimmed enough so that the world is actually still ok in the end. 

In addition, there are forces for good from all of fiction present too. They are helping to balance things out.
