From a scientific perspective there is some indication that a nuclear war could deplete the earth's ozone layer or, less likely, could bring on a new Ice Age - but there is no suggestion that either the created order or mankind would be destroyed in the process.

If one considered life as a simple loan, one would perhaps be less exacting. We possess actually nothing; everything goes through us.
