OOPS. * Reeling from the Black Death, Europe's peasants decide it is cats that are carrying the plague, and start killing them off . . .leading the rat population, which is really spreading the disease, to explode. * A better society is Prohibition's goal-but the result is robbery and homicide, plus the use of cocaine, marijuana, and opium as substitutes for alcohol. * Mexico invites Americans to Texas. And the Americans never leave. * Nixon has a twenty-point lead in the polls. Apparently that's not a comfortable enough margin for those who decide to ensure his success . . .by breaking into the Watergate. From the Maginot Line to the Bay of Pigs invasion, history is filled with bad moves and not-so-bright ideas that snowballed into disasters and unintended consequences. This engrossing book looks at one hundred such tipping points. Japan bombs Pearl Harbor. Rome farms out its fighting to barbarians. The Aztecs greet the conquistadors with open arms. And the rest is history . . .
