Teldrassil: Sylvanas nukes it, smiles while doing so, gets away with it, later on is besieged, cornered, surrounded by the Alliance but somehow still escapes while giving the middle finger to the Alliance, somehow still keeps control of the Horde even after all the mess with Garrosh ON TOP of the 2 war crimes she already committed (this is just the pre-patch of BfA btw), still keeps popular support until she tries to kill the burger Baine, then when she betrays literally everyone she STILL gets away with it and doesn't die, is in the process of being redeemed while Elune tells Tyrande to stop being angry that her people got exterminated.
So Yes, the Horde committed genocide twice and got away with it twice while looking good and badass.
Meanwhile Jaina kills 20 elves in Dalaran once and the entire Alliance (in-universe), Horde, and community hates her, it's clear that the Alliance is never allowed to have balls. They can't even make incidents, Alleria does an oopsie at the Sunwell and everyone treats her like she's the second coming of Satan. Meanwhile we got the Forsaken experimenting with the living and developing dangerous toxins since Classic but no one cares.
The Alliance is literally neutered. But now that Turalyon is High King hopefully they will take a more direct approach. Which doesn't equate to committing genocide, but it does equate to not let the Horde walk on them any further. And by "walk on them" I mean "stomp them and grind them to dust".
