Could you be more specific? Overall, the worst we can face is a zero-percent chance in some circumstances I can't predict. The best is a forty-seven percent chance if we manage to not only stop the war from leaving the galaxy it's currently stuck in, but also have all of both sides wiped out and all of the most powerful undecideds join us.
