50 years ago, when I wrote “Slime Wars”, I said — somewhere in the 300,000 word science fiction novel — that people wouldn’t believe my visions of nazis, tanks and soldiers on the streets of America, until they could see it for themselves, at which point, it’s too late.
Well, too late or not, you’d better brace yourself and at least minimally prepare for a short period of inconvenience and short supply which could easily extend through a period of some 30-40 years of constant combat.
