"What I will tell you is if you pursue this war of yours, it will end badly. Not for one side or the other, but for all involved. Even scientifically, if you continue to destroy mutants as they evolve, soon there will be no human race left. The gene pool will be too weak to continue on its own." Of course that was assuming humans came out on top in the end. And Charles was just buying time by talking, he knew that. "Is this personal for you? You've had interactions with mutants before...." Stripped of his abilities, Charles was still a smart man...and there was always psychology that could be used.
