Ah, you mean Pax Purpalia? It would be nice to see Alliances finally pay the tribute that we rightfully deserve.
On a more serious note, I've said this before, and I'll say it again. There will be no United Alliances, no League of Friendship, and no Council of Orbis. The only way anything will ever come close is if a hegemoney exists and the other alliances rally against it (ala (That terrible game that is totally irrelevant and I shouldn't be bringing it up anyways) Karma War) and even then it will only be a temporary measure and will break up after the war is over.
