No, you can't have sloshed sailors handling sub-launched ICBM's, but equally, to remove the entire ration of aptly named Nelson's Blood is throwing out the baby with the bathwater.

Sometimes the responsible use of alcohol can steady combat nerves and actually reduce the fear factor, which on it's dark side, can lead to panic-initiated mistakes.
A great book.
