"We’re human beings, with the blood of a million savage years on our hands. But we can stop it. We can admit that we’re killers … but we’re not going to kill today.
That’s all it takes!
Knowing that we’re not going to kill today." *
-- Captain James T. Kirk
...And, as they say in recovery, tomorrow's not looking too likely either.
*We might, however, make grown men wear rubber galoshes on their heads.
