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.

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...
