Much of the propaganda being put about by the Empire and its supporters is just too facile by half. It smacks of rationalization. Excuses. It's more "scare tactic" language.
It's easy to talk about "biding our time." For what? "Until the Empire is stronger...." Yeah, right. Go on, pull the other one.
But the Thalmor are biding their time too. They're also getting stronger. They are actively seeking to undermine any sense of unity or self-determination that the people of Skyrim might have or develop. And to that end, they have spies and active agents in Skyrim.
But most importantly, they are determined to wipe men off the face of Tamriel...or so they say.
Will the Empire "bide its time" until the AD is powerful enough to actually accomplish that goal?
Or will they suddenly grow a pair and, and...and what?! If the AD is powerful enough to exterminate all men, will the Empire be strong enough to stop them? If so, it will be the first time in human experience...real or imagined...that such a scenario bears fruit.
So put the extermination bit aside...it can't be true, can it? Surely, no one could be so cruel. It must be a mistake.
That kind of thinking is la-la land self-delusion...all in the service of appeasemant and expediency and preserving their own privileged positions as long as possible. Unfortunately, we do have many RL examples of just such perfidy.
The Stormcloaks want to revoke the WGC and drive the Thalmor and all AD agents out of Skyrim.
The Thalmor want to wipe out human beings. The Empire is, willingly or unwittingly (more fool them), aiding and abetting that enterprise.
The contrast is startling...if you just look at it square on.
BTW, William Wallace didn't have the full support of the Scottish people either...despite the movie representation (and, sorry, there were no...zero...kilts at the time either).
Nor did George Washington, have the full support of his people at the time of the American Stormcloak Rebellion.
