[Star Wars] Would the imperium survive if Vader managed to overthrow Palpatine somehow? How would his reign be?
gpt
No. Two reasons:

Operation: Cinder. Palpatine had the building blocks in place for the First Order/Final Order to rise in the event of the Galactic Empire's fall, because he felt that an empire without him at the top was no empire at all. The FO and the Empire would have started fighting each other eventually if Vader's empire lived that long.

Vader had zero patience for politics. He would have dissolved the Galactic Senate even sooner than Palpatine did. Then he would've kept his hands firmly off the wheel and let the moffs (Tarkin especially) run things. Since Tarkin's doctrine was basically "squeeze the local systems until they break," rebellion would likely have sprung up much sooner. Except it would probably look closer to Saw Gerrera's vision than Organa and Mothma's.
