Which is between the Son'a and Baku, which is why crazy admiral guy called the whole thing off. Hell the federation didn't even know about that.
So if the S'ona wanted to exterminate the Ba'ku and take the metaphasic radiation, that would be cool in your world?
Like I've said a hundred times before in these threads, the Federation's actions likely prevented the Ba'ku from being exterminated.
Not all the Son'a were blind followers of Rua'fo. Gallatin for one wasn't too happy with him when he wanted to exterminate them.
"Moving them is one thing. Killing them all?!"
There probably were more Son'a who felt this way. Some of the Ba'ku were their parents afterall.
