I really needed to? I like altmer/bosmer and thus prefer the dominion and thalmor out of all the current factions, if I personally had to take a side in the rebellion (which was the main question of the thread), I would go with the empire as that seems to me to be the better outcome for the thalmor. The rebellion has served its purpose and damaged the empire, but stormcloak rule would do more harm than good for the thalmor cause.

Technically, a Stormcloak victory is a bit more ideal for the Thalmor, since it further diminishes the Empire's strength, and isolates Skyrim for a later time. Sure, the Stormcloaks will probably kick the Thalmor out of Skyrim, but when the time comes to go to war with the Empire again, the Imperials will only be able to call upon the strength of High Rock and Cyrodiil (which saw the bulk of the fighting in the war where as the Dominion is largely untouched) without the manpower or resources from Skyrim. The Empire technically still has control over Morrowind, but it also was occupied by the argonians and has suffered a massive natural disaster, so it's not exactly reliable at the moment, whereas the Dominion can call upon the Summerset Isles, Valenwood, and Elsweyr to go to war at any time, and I do need to stress that as the invading party that had the truce signed heavily in their favour, they're sitting at a huge advantage. If they win that war against the Empire, then chances are, Skyrim will fall in due time when the subsequent war breaks out.

Honestly, I wouldn't be surprised in Elder Scrolls VI if the Aldmeri Dominion was dominating most of Tamriel.
