Colin S. Gray quotes:

American strategic [nuclear] forces do not exist solely for the purpose of deterring a Soviet nuclear threat or attack against the U.S. itself. Instead, they are intended to support U.S. foreign policy.

Peace is not achievable as a direct object of purposeful behaviour.

It was no picnic despite what anyone might say later . . . . Most of us were pretty scared all the bloody time; you only felt happy when the battle was over and you were on your way home, then you were safe for a bit, anyway.
