As a big fan of the whole Foundation saga, I don't remember any wars in "Robots and Empire" 3 books. Granted, those were the only books I've read only once (and a long time ago), but I'm pretty sure there was no war.
The way the most recent season of the show ended it looks like humanity may have been misled about the war, so it may end up fitting that more closely once they're done (I haven't read any of the books, just going on your comment).
