The player is the best diplomat in the world, there used to be continuous global wars and now everything's running so smoothly, that neither gods nor the most hardcore religious followers don't even go outside their village (or in whatever hole they reside) anymore, aside from some NPCs showing up throughout world events and quests.
We're the greatest threat to others' autonomy, I mean look at how much havoc was wreaked throughout the ages, yet we're the only ones that have talked to and helped gazillions of NPCs simultaneously, which resulted in their susbsequent organization throughout adverse events.
It's clear that the very fact of us being here is keeping the whole system from collapsing, as any arrogant piece of s#@t pointing a finger at us or our allies would set off a cascade of events that would result in the systematic destruction or weakening of key disturbing elements (Sliske, Tuska, Bandos, etc.).
Rest assured, everyone else has clearly gotten the message that they shouldn't mess with the World Guardian, or their whole power structure's going down. This is why you should sit back, relax, look at what you've achieved and cherish it, without thinking of why some things you fear haven't happened, cause you'll always get things done, no matter how grave they are.
