What does that matter? They still have Valenwood. Thats a loss for Bosmer.
Wow dude, okay. I'm done arguing with someone that doesn't even take into consideration the fundamental differences between the Thalmor and the Empire.
For the record, the Bosmer were a part of the First Aldmer Dominion, and it was different then. The people who chose to support the Thalmor this time, probably remember the good old days when the Dominion prospered.
