I've lived through a few coups. They're insane, random, and terrifying, like watching sports, except your political future depends on the score.
The kickoff begins when a key official decides to buck the executive. From that moment, government becomes a high-speed head-counting exercise. Who's got the power plant, the airport, the police in the capital? How many department chiefs are answering their phones? Who's writing tonight's newscast?
When the KGB in 1991 tried to reassume control of the crumbling Soviet Union by placing Mikhail Gorbachev under arrest and attempting to seize Moscow, logistics ruled. Boris Yeltsin's crew drove to the Russian White House in ordinary cars, beating KGB coup plotters who were trying to reach the seat of Russian government in armored vehicles.
