I just want to comment that. The problem with this mindset is that the Dominion was not only driven away from Gnox (and we don't know if they ever dared to came back on this planet or not) but they unleashed the Granok at a galactic level. Instead of letting the Granok rot on their world, the Dominion arrogance insured that the Granok veterans who broke the back of the mighty Legions of the Luminai were able to just do it again, and again, and again on multiple battlefronts. As for the Aurin matter : once again it was a stupid idea. Not only it cemented their reputation of invaders, genocidal maniacs and untrustworthy galactic power, but it had probably led a lot of young people among the unaligned planets able to travel in space to band with the Exiles to get ride of the Dominion.
