Why does everyone keep saying this? while the empire got its ass handed to them for awhile the treaty was after the empire CRUSHED the Thalmor army in a big battle
It's because a lot of people have little idea of how strategy or war works.
To quote myself again...
Another thing that I see you Stormcloaks say is that the Empire "gave up" or "surrendered." They didn't, they sued for peace.
Had the Empire surrendered or given up it would have been at the point of the Thalmor sword, it was not. The Emperor and the Legion took back the Imperial City and sued for peace with the Dominion. Yes it was the same contractual terms as the original surrender was for however if the Thalmor had the Empire at the point of its sword the terms would not have been so, the peace treaty would have been even worse.
Since the Empire was on the offensive however they were able to secure that deal. They're wise enough to know however that unless they sued for those exact terms it's unlikely the Dominion would have accepted and the war would've raged.
The Empire sued for peace they did not give up. They hit the pause button that happens to have a few rules. Once they recover though its game time again.
For those that think Skryrim is some how magical and can face the entire Thalmor army by themselves, again face the facts...
That demonstrates my example of a Stormcloak lacking any planning or foresight ability. Fighting to the very bitter end is not how you preserve am Empire. That's how you'd destroy it.
The Empire, as has been stated many times, is binding its time until it can again attack again. The treaty is not going to last forever. The Empire, when it recovers will strike back against the Thalmor, or if the Thalmor recover first because of the meldsome Ulfric they will attack and take over both the Empire and Skyrim.
Skyrim won't survive on it's own. Sure the Redguards have held their ground however they have not driven them out, nor have they won. They are also battling the already bloodied Thalmor armies after the Legion gave them black eyes. Were Hammerfell to stand against the full might of the Thalmor they would not survive, the entire Empire barely did. Skyrim is no different.
Redguard is surviving by the skin of its teeth. They have not defeated the already weakened Thalmor nor have they push them out of their lands. The Redguards are very much akin to the war in the middle east currently. They're resistance fighters, that's it. Skyrim would be no different. Skyrim cannot stand alone, nor can Hammerfell.
