All right, you guys have read through almost everything there is to see with regards to the current political situation of the human race. The first three articles covered the history of the Alliance -- both old and new -- and the struggles of Varian Wrynn and his life as the "leader," so to speak, of the human race. The word leader is used in quotation marks because, to be perfectly honest, Varian wasn't much of a leader; he was brooding, depressed, not really willing to see anything that was going on around him, and the Council of Nobles was pretty much running the show.
The only "real" leader available to Alliance humans at the outset of World of Warcraft was Jaina Proudmoore, the leader of Theramore, who wasn't really much of a leader either. This was largely due to her somewhat unpopular beliefs that orcs were capable of peace and her attempts to work towards some sort of peaceful agreement between the orcs and humans of Kalimdor. So here we have the human race, largely left to its own devices -- but they seemed to be doing, if not amazingly well, at least OK for the most part. It's Varian's return and the events of Wrath that directly affect what's going on headed into Cataclysm.
