It's actually an interesting question (that Blizzard has no, repeat no, intention of going down). Can the orcs be redeemed? Everyone insists yes but historically, no, they can't. Blizzard has written a race that almost always does the wrong thing.
Thrall, the entire Saurfang line (Brox, Varok, and Draenosh at the Wrathgate), Eitrigg, even Grom. All of them, ultimately, have either done the right thing or have proven themselves to be squarely on the side of good. The problem, right now, is purely Garrosh and his Dark Horde refugees.
But the idea that Org is a win is equally pure and unbridled speculation. We don't know. Well, I don't, I assume you're not a Blizz employee so I assume you don't. My speculation that it could be a disaster is as completely valid as your assumption it's a victory. And you really didn't want to bring up Eisenhower because...
We must assume it is a victory for both the Alliance and the rebel Horde because anything else is going to leave both sides bitter. I'd rather play the optimist than the pessimist because, quite frankly, I don't feel like brooding for two years until the Siege drops.
Speculation, by the way. There's been a number of people arguing that the Horde should get the kill shot, not the Alliance. Vol'jin and Sylvanas tend to get mentioned. So you're as desperately speculating as I am.
Perhaps. In fact, maybe this is what keeps the war going. The Alliance captures Garrosh, but Vol'jin stabs him the back, infuriating the Alliance. Obviously there still must be tension for the PvP game to continue. However, I would be extremely surpised to see Varian not have a major hand in Garrosh's downfall. Blizzard has built that rivalry up to the extreme, and I honestly cannot see them dropping at the climax of the story.
Let me check something. Did Eisenhower get the news of Hitler's death, cheer and then pull everyone out of Germany? Did the Soviets find Hitler's body, call it a day and evacuate Berlin? (Oh, and using WWII comparisons when talking about not targeting civilians is really, really counter-productive) That would be no. Because Hitler wasn't the sole reason of WWII and killing him wasn't the ultimate fix. It took a complete rebuilding of German society from the ground up. That is so not going to happen here. So no, the Alliance is not Eisenhower-esque.
Then let's drop the analogies completely. Do you really believe that, after everything that has been said, Blizzard is just going to let the Alliance hang out to dry? All because of a supposed bias for the Horde due to one, poorly-received expansion? If you have so little faith in Blizzard, why are you even here arguing about it?
