[Star Trek: DS9] What happened with the Dominion after the Dominion War?

So their forces in the Alpha Quadrant had to surrender and most likely withdraw. But their main empire would be in the Gamma Quadrant and would quite possibly be undefeatable by the Federation and it's allies. Sure, they can not move through the wormhole without Sisko's permission, but are they still expanding their empire in the Gamma Quadrant?

And what of the Breen? Are they still Dominion allies?

Breen: What happened to German allies after WW2? They have restrictions on what kind of military buildup they are allowed to do. But the Breen were not IN the federation so the federation's authority to do much to them beyond monitor and not let them build up their forces is it. There might be like some trade embargos with any federation colonies or worlds BUT as stated, it's not like there was much of that going on with the breen before the war. 

Dominion: Yea they can still expand in the Gamma quadrant.... so what?  But their forces are crazily depleted. However.... Foolish to assume  that they didn't send a small force to take the long way around since they are all about the long game, however by the time it gets there the tech on the federation side will be much improved.
