The Cardassian POV from the Occupation is "Bajor belongs to us, everything from Bajor belongs to us."
After the Occupation is "Psh, you think we're gonna give stuff back?"
A couple years later is "Hmm, the things are useless to us but valuable to the Bajorans. Hey let's use them for our political and financial interest!"
And after the war is "Oh, that Dominion alliance thing? Trying to conquer the alpha quadrant? That was Dukat, not us. Orbs? Yeah, they totally belong to Bajor, of course they do! It was the bad Cardassians who stole them. Please don't kill us. Hey, let's make an alliance!"
