I don't think Eddington was as genuine as he presented. I think he was a master manipulator and looking for a cause to support his ego.I wonder how much of that was his own ego and how much was just egging Sisko on further.
But he was genuine, and I would love to read about a defiant Eddington declaring a Maquis State on the Viewscreen after crushing the Cardassians, whupping the federation, and leading his troops to victory.
Also, I think we saw that movie. It was called "Star Wars."
The Founders had the Romulans and the Cardassians pegged from the word go. There was a great episode, "The Search" were the Dominion set up a virtual reality to test how different members would respond to a peace treaty with the Dominion. They already had a fairly decent idea about how each race would respond, which you don't get from brief observation. Once the plan was learned by the Founders, it was only a matter of time.Can't say I really read the Maquis that way, they were a fly in the ointment for the Cardassians and the Federation, whose primary threat was they might provoke a full scale war between the two. I never saw them as really standing much chance of hurting the Cadassians much outside the badlands.
I'd say the founders did a pretty good job of making their own luck there. The infiltration tactics worked time and again for them and they readily got into the most secure privy councils of pretty much every known AQ power
Which takes his cause from a "defend our homes" to genocidal levels of awfulness. Which, brings me back to the point that Eddington turned in to a egotistical jerk, with delusions of superiority, that nearly dragged the Alpha Quadrant in to a war.Had the acquired or developed the weaponry to do so then yes they would have and I think with the necessary "back channels" statehood declaration, and the Maquis's own resourcefulness could have cooked something up that would have turned Cardassia into ashes.
