“The 'realist' conception of continuing old-fashioned 'balance of power' politics may have been well founded in the past, but it is inconsistent with our increasing interdependent world. On moral grounds alone there can be no justification for the 20th century level of killing. To settle disputes without violence must become the primary goal of foreign policy for every nation.”
Robert McNamara
“A great civilization is not conquered from without, until it has destroyed itself from within. The essential causes of Rome's decline lay in her people, her morals, her class struggle, her failing trade, her bureaucratic despotism, her stifling taxes, her consuming wars.”
Will Durant
