I forgot to mention that while the Thalmor now know Skyrim better than they did Geographically, they still do not know it nearly as well as the Nords and never will. Attacking Skyrim could cause more problems for the Thalmor than solutions; as well as everything I have already mentioned, they risk bringing Hammerfell into the war if they attack Skyrim, who would most likely fight the Thalmor if Skyrim was attacked, especially if Ulfric wins the civil war because then the Redguard would have the same goals as Skyrim, and a Nord win, especially a quick one could very well weaken Thalmor morale and make the Thalmor tally 1 win and 2 losses and give the Empire more inspiration to take up arms again.

Also, I haven't touched upon Dovahkiin, who would be a brilliant asset for Skyrim, holding Thalmor forces at bay and calling Dragons to his side. The reason the Dragons are more likely to attack Thalmor is not only because of Dovahkiin being against Thalmor, but also because the Thalmor are new to Dragons and would not be prepared for them, making them more vulnerable and thus an easier target in Dragon eyes.
