Just wanted to clarify a point made by tbh: "The orcs see humans as the people that held them in internment camps for nearly 20 years, something they'd rather not repeat. Though a special bit of blame is on them since they won't admit that they were wrong in trying to slaughter the Draenei or taking Kalimdor away from the Night Elves, because they high on some manifest destiny which they believe gives them the right to take which was never theirs."

I dont believe this is an accurate representation of the Horde. Thrall makes a very clear distinction between his burgeoning empire and the Horde of old. He describes his new Horde as different from the brutal murderers of the past, and as such I believe he would view the slaughter of the Draenei as a contemptable act.

Similarly, I believe Thrall wasn't so much looking to take Night Elf territory, more like they were plunged into hostilities by forces beyond his control. Thrall didn't know that the Night Elves even existed when he ordered the Warsong clan to start chopping down trees building fortresses, and the whole thing was made even worse by Hellscream's second corruption and the following slaughter of Cenarius. Effectively the Orc-Night Elf feud occurred without Thrall being involved at all. I believe that if he could, he would be perfectly willing to find a way to coexist peacefully. After all, he made peace with the Tauren and native Ogres quite happily. He also happily made peace with the Night Elves and Jaina's forces of humans when called upon to do so. It was the subsequent actions of Daelin Proudmoore and other political events that led to the continuing hostilities.

So, whilst the Horde are not exactly wusses, and admittedly have been ratehr expansionist towards local Centaur and Quillboar, I dont think its accurate to lay this kind of blame at their feet.
