Once upon a time I was involved with review of this kind of planning. Back then it was estimated that execution of a complete "laydown" on both sides would result in the first days in 40 million dead in North America and 60 million dead in Eurasia (USSR basically). These estimates did not include later death from radiation poisoning, starvation, etc. Ah, yes, and then there would be the end of civilization as we have thought of it.
All that should be considered by the president before asking for "the football." pl
