Chapter X: Immediate Aftermath, 1983-1985.
Meanwhile, things in Europe and the former USSR were even worse than in the United States. Many of the same things occurred here such as the disappearance of basic amenities, lack of medicine and basic hygiene standards, lack of technology, low levels of modern communications, limited infrastructure, fuel shortages, the breakdown of law and order, reduction of the economy to pre-industrial levels, famine, epidemics and the government using remnants of the armed forces to establish small safe havens. In Britain, the essentially feudal economy was emphasized by the fact that the government and the royal family relocated to Portchester Castle, a baronial medieval fortress built in the eleventh century in Hampshire, England (fuel and food ran out in the Central Government War Headquarters after three months). Portchester became a metonym for the British government in fact.
Compounding the disastrous population die-off through famine, deprivation, chaos and outbreaks of cholera and typhoid was that the Soviet Union had used its biological weapons arsenal as a parting gift in the final hours of the war. Outbreaks of anthrax, smallpox, the bubonic plague, tularaemia, Q-Fever and Marburg Virus resulted through the release from stocks of the Biopreparat agency. Particularly the plague, long thought to have been exterminated in all but Third World countries, spread like wildfire across Eurasia and parts of Africa due to lack of hygiene, weakened immune systems due to famine and fallout, the absence of public sanitation and garbage disposal, the subsequent spread of vermin like rats and of their parasites (lice and fleas) and the total lack of basic antibiotics like penicillin. All of this combined raised the total death toll of the Third World War to one billion in the two years that followed it.
