I don't think i'm missing any point. Winning is winning. Let's not forget both Starfleet command and the Federation Council voted AGAINST giving the Founders the cure for the morphogenic virus. They were content to ride it out and hope for a speedy end to this war. War is ugly and the Federation were losing it. While biological warfare is the lowest point you can stoop to. Drone warfare is not. It relieves the stress of combat for humanoid soldiers. Even today it's seen as a tactical advantage over send troops in to die.
