This ignores the fact that the Zandalari were the enemies of both the Alliance AND the Horde before Sylvanas decided to use Talanji and Zul to ingratiate herself with Rastakahn for her navy.
Or did you forget about the time where Zul’jin even asked the Alliance to help deal with the Zandalari, or when the Zandalari raised Lei Shen?
Yeah, pretty much. The Alliance are VERY clear victors in the Battle for Dazar’alor.
