are Dominion.
Well of course they are.
Yknow what made the Dominion so frakkin great? That scene where Dukat and Damar are cackling about how the Dominion treaty with Bajor is just a stupid piece of paper that they can't wait to violate, and Weyoun smacks them down and puts them right in their place.
That shows that the Dominion really
thinks - they want to use the treaty with Bajor as an example to the Alpha Quad that they really can be trusted, and from what we know, the Dominion treats subject words in the Gamma Quad pretty well, giving them protection and allowing them to trade and prosper, and all they ask in return is that nobody kicks up a fuss.
Because you can trust the Dominion not to plunder your planet, right? I mean what the frak does the Dominion want? Besides peace and quiet, apparently nothing. The Founders slosh around in their pond, and the Vorta and Jems have no interests outside of serving the Founders. They don't even have very wide-ranging tastes in
food and therefore wouldn't even swipe your food supplies, much less anything else. They don't drink, no sex, no appreciation for art, no appetites for anything at all. Talk about your ideal alien overlords!
And that is what makes them so incredibly dangerous to the Federation - what they offer is a pretty attractive alternative to the Federation. You give up some freedom but get more ruthless protectors. Who would be better against a Borg attack, those Starfleet chickens or the Dominion, who are incapable of cowardice because death means nothing to the Vorta (hey there's always the next clone) or the Jems (death is the point of their existence)? My money would be on the Doms.
I might have to change my vote!

Cardies are such losers.
