Thanks for posting, indeed, a very sobering read. Much of the early part focuses on technical and physical aspects, and I'm glad it later details the effects on people. But the best part to me is the last 2 paragraphs in italics which describe the real possibilities of nuclear strikes and war today.
If you haven't seen it folks, the movie THE DAY AFTER is, I think, while old [24 years?] worth watching. It shows the utter devastation a strike would cause on the USA and is known to be quite realistic.
