No, as of the end of Shadows Rising, Talanji hasn’t forgiven nor forgotten the acts committed against her by Jaina or the Alliance. The novel ended with her realizing that being consumed by vengeance and hatred would only harm her and her nation in the long run.
The Alliance and Horde who are participating in the exploration of the Dragon Isles signed an agreement to work in cooperation with one another, so you can assume that the select Night Elves and Zandalari present don’t have any hang-ups about it.
He was living on borrowed time anyway because of the deal he made with Bwonsamdi. I really liked him, but he had an excellent sendoff. He went down swinging like a boss. Very few major lore characters get that sort of treatment, so with him being a side character of sorts, he was extremely fortunate.
You’re supposed to believe that, like responsible adults, they’ve realized that getting millions of people killed in a renewed war just to soothe their own grievances would be childish and unworthy of their exalted positions.
Now I do not, for a moment, believe Tyrande actually is that responsible - she never has been before - but that’s the theory.
As a distraction to get away yes a necessary sacrifice
That isn’t a justifiable reason at all like comparing that to real world events it is basically the equivalent of the Irish capturing and imprisoning a random British person they find because of past actions of the British.
I mean it’s not like fighting the Zandalari is some event buried deep in the past. They were enemies in multiple raids in Pandaria, which was only like four years before BfA.
And depending on what Irish person you ask they’d probably find imprisoning random Brit tourists to be a pretty reasonable activity anyways.
I’d rather we just pretend the BfA war didn’t happen tbh. Everything written after Legion has been bad fanfiction with a small handful of standout characters like Bwonsamdi and Denathrius.
Both factions were working WITH the Zandalari to attempt to prevent the other tribes (primarily the Gurubashi) from succeeding in bringing Hakkar physically into this plane of existence. That was literally the entire point of ZG. And then again in ZG during Cata when Jin’do’s spirit forced it’s way back onto Azeroth and reunited the fractured groups of remaining Hakkar worshipers to try to manifest the blood god physically onto our plane of existence a second time
There were also Zandalari in Notherend during Wrath (originally going there for archaeological/history gathering purposes) attempting to fight the Drakkari once they started throwing in with Arthas.
That was a splinter group that still held to their old alliance/subservience with/to Lei-Shen (that had kicked off more than 11,000 years ago and that had been over for almost 10,000 years after he died trying to conquer Uldum). That batch of Zandalari were the ones who were still in Pandaria after the rise of the Pandaren Empire and the Emperor creating the Mists.
