2080 notwithstanding, this book does very little to introduce the subject of a future war.
Sure, the author IS a scientist and sure, it was involved in weapon's research but apart the - very interesting, for 1979 - chapter on nuclear weapons, this book is absolutely lacking any data, nor it postulates any of the - now accepted - theories on future weapons and/or warfare.
Like too many physicists before him, Langford uses too many times the words "impossible", "unfeasible", "improbable" and so on, on various subject now widely accepted (and/or existing) like laser weaponry, electromagnetic artillery and other staples of "science-fiction" weaponry.
After reading the book the question arise: "How in the world did we reach our actual level of scientific development, if our own "men of science" do use so many often so many "imp-words"?
But the most risible aspect of this book is the author arguing at lengths in a - rather boring IMHO - discussion on the "very realistic" aspect of future warfare, like smashing planets with "planet-busting" asteroid-weapons and black hole generators... a really, really REALISTIC scenario, don't you think?
Not bad for a scientist who dismissed only a chapter or two before the reality of laser guns and particle small arms or the use of antimatter in warfare.
