In a society that sells hot drinks with cardboard barriers to avoid law suits, where safety regulations and legal disclaimers have been raised to a high art, does anything important ever happen the entails real risk and uncertainty?

Our ultimate triumph in Iraq may be certain, yet the potential for tragic setbacks is terrifyingly real. This shocks us, and awes us as well. It may also change us.
