I mean... kinda?
Anduin acknowledges in his letter in Before the Storm that the Horde and Alliance aren't at peace. He calls for a Cease-fire for a single day. Meaning the War is already happening, and he's willing to stop attacking for 1 day.
You could argue that it's just "Hostilities" but with attempted regicide and a sneak attack during a Truce to fight a larger enemy? That's a bit more than Hostilities.
When you are accustomed to privilege, equality feels like injustice.
Genn is technically a king, of a shattered kingdom obviously but still a king. I do not view him as some sort of passive lapdog that will just roll over because someone less than a quarter his age told him to. He has, and will continue to likely, make decisions that go counter to what Anduin wants because of his own beliefs.
Ok so using this logic the Orcs, Tauren, Trolls, Nightborne, Highmountain, Goblins and Sindorei should be morally allowed to just slaughter the forsaken straight out of the horde and existence because they are perceived as evil and this would be justifiable to you? I mean I would like it but it isnt a good act even if it is a beneficial one.
Then he has no business being a commander of non worgen alliance forces, when hes in command of the skyfire or leading an alliance force he is acting as an alliance officer and any action he takes is a action performed by the alliance. unless hes declared an outlaw or in some way disavowed and actually punished his actions are part of his factions.
At this point Sylvanas fan can consist of only two types:-
1.Forsakan/Undead Player in Horde because Sylvanas will only help undead , "for the horde" by her is just a lie
2.Player who like too much female animated character, nothing good(in head) can be said about these players
That's part and parcel of the problem as to why the Horde is on a war footing in BfA - Genn was able to make an attempt on the life of the Horde Warchief in an action that didn't have Alliance sanction, but the High King of the Alliance neither punished nor formally censured Genn for his actions in Stormheim. This, to a large degree, is how Sylvanas is able to sell her war to Saurfang - crouched in the terms that peace with the Alliance was a brief and tenuous "dream" that would soon shatter in the faces of the Horde leadership. Better to conclude such a conflict in the favor of the Horde well and before the Alliance could encircle them given time to build back up after the Legion campaign.
"We're more of the love, blood, and rhetoric school. Well, we can do you blood and love without the rhetoric, and we can do you blood and rhetoric without the love, and we can do you all three concurrent or consecutive. But we can't give you love and rhetoric without the blood. Blood is compulsory. They're all blood, you see." ― Tom Stoppard, Rosencrantz and Guildenstern are Dead
He was the senior presence aboard the vessel - the highest officer of the Alliance, you could say. The Skyfire was nominally under the direct command of Sky Admiral Rogers, but she was very much subordinate to Genn's command (though she also agreed with Genn's stance i.e. the Forsaken).

Also because Taurajo was a mistake of kindness. Alliance Commander in charge tried to be kind and not take civilian prisoners. Note the Quilboar that the Horde had been committing acts of genocide against since Orgrimmar and Thunderbluff had been founded, took the opportunity to kill Tauren stragglers who the Alliance created a weak point in their military lines on purpose to allow the Tauren civilians to flee. Camp Taurajo was also attacked after Garrosh started the all out war with the Night Elves, as Theramore attempted to aid the Night Elves.
Camp Taurajo is literally the only "bad" thing the Alliance has done in its history.
The attack in Legion by Greymane was entirely justifiable. Genn attacked Sylvanas' ship. He didn't perform any aggression towards any other Horde forces, specifically Sylvanas' ship. There is serious plausible deniability on his part for the state of the Horde at that point, because as we learned in Before the Storm, the only message the Horde sent to the Alliance about what happened on the Broken Shore was a secret letter sent by Baine that said, "We were ambushed we had to retreat, we didn't mean to abandon you and I'm sorry your dad died because of it." Sylvanas didn't even attempt to open any lines of communication, she just ignored every comment that the other Horde Leaders made about how the Alliance would be upset and might retaliate over the apparent betrayal. Sylvanas created the Stormheim conflict by purposefully keeping silent and not trying to foster cooperation between anyone. She isn't an idiot, she didn't just forget. She wanted and wants hostility towards the Alliance because she wants fresh corpses. She wants free cannon fodder to keep her Forsaken and herself sake, she gets that from fresh dead.
The only time the Horde wasn't actively seeking genocide against anyone that wasn't giving them open tribute was when Thrall and Vol'jin were in charge of it (even then that is still up for debate since during that time they were actively trying to exterminate every Centaur and Quilboar in their territory). At every other point in history, an entity that called itself "The Horde" would go on genocidal rampages until it was defeated and dismantled.
What are you willing to sacrifice?
Dude dont pretend Genn's punishment or its lack of has something to peace. Quoted statement sound like its coming from the guy who was triggered by the fact that Genn cucked Sylvanas for free. I understand the feelings, but lets not twist the facts.if anduin wanted real peace he would have given greymane a harsher punishment then "bad dog very bag dog!"
Right Rogers, i dont know why i mix her with Jes tereth. I dont play alliance enough to keep them straight. I havent actually seen the alliances side of that zone so I was just operating under the assumption that Genn was kinda just there because he heard Sylvanas was there so he was like IM GOING.
Blizz did a decent job in making sure noone's hands are clean.
The wise wolf who's pride is her wisdom isn't so sharp as drunk.
Real global politics are touchy. Generals get fired for getting too drunk in public if its perceived it will bring discredit to the military.
Azeroth has Horde, Alliance and a bunch of small groups noone cares about. Alliance generally unilaterally hates the Horde so why would the general populace want Genn shamed for what he did, its not like they care what the Horde thinks. There isnt some global relations to manage.
The only peace Anduin ever wants is to stop killing each other over dumb shit. Geographically nothing would change, Sindorei wouldnt suddenly start living in Stormwind if he got his peace we just wouldnt fight each other over petty shit.
