Planetary Defense

An interesting foray into the what-ifs and why-fors of preparing for an extra-planetary attack of some sort or another. This book not only delves into the hows and whys of a "classic" alien invasion (as seen in science fiction), but non-standard approaches that should be accounted for. For example, the book also deals with: preparing for collisions with Near Earth Objects; preparations for civil defense, in the case of natural disaster; dealing with a resource depletion scenario of our own devising by reaching out to the stars. I recommend this book to: * Science fiction authors * Civil defense planners (not only federal, but state and local) * Military history afficionados * Wargamers * & anyone else involved in strategic or tactical planning that I might have left out.
