After we talk about reparations for what the war brought on to the Zandlari, the assault and murder on Goblin refugees, the repeated genocidal attacks on the Tauren and the Forsaken by the Alliance. Then you can come back.
As for the Night Elves… they brought their fate on themselves. The Night Elves spent millennia banking up bad karma and the bill just came due.
Reparations are what you squeeze out of a defeated enemy. The Alliance did not even come close to beating the Horde.
