It's easy when taking an overall look on World War II for history to concentrate on the major players, Britain, USA and the USSR for the allies, and Germany, Italy, Japan for the "bad guys" let's say.
But of course looking at this you see there were dozens of minor countries also in play

From looking at Memory Alpha I see the novels had the Gorn fighting on the Allies side-

So is it possible that in the Dominion War there were other independent species on the Allies side besides the UFP, the Klingons and Romulans? And if so who?
The Tholians and Miradorn took out non-aggression pacts before the war started, so I guess you could count them out. I always wanted to see more of the Children of Tama (Tamarians) from TNG: Darmok. Their ships were just as if not more powerful than a Galaxy class vessel, and with the improved dialogues since that episode it'd be cool to have them helping out
"The beast at Tanagra. Uzani with fists closed"
Also wasn't there a thing in DS9: "Valiant" that Nog was on his way to Fereginar to present the Nagus with a proposition from the Federation to help out in the war. But that plot strand seemed to be quickly forgotten. The D'Kora class Ferengi Marauders seen in TNG were pretty tough, with Ferengi space so close in Cardassian/Dominion territory it would seem they should have considered it when the war was going badly.
Any other suggestions?
