This world was always plagued by widespread inactivity because of the poor settings, so I'm not sure that a true war (on the scale we've seen in other worlds) has taken place after the first 4 months or so.
Even by the time Who? fought the southeast, activity levels were pathetic. I doubt there were more than 40 active participants in that entire war.
BTW, it was never Who? vs. the world. The Scientists were supporting you, which was a massive benefit given the fact that most of Who? was inactive by then.
