Zbigniew Brzezinski : Advisor to Jimmy Carter, President of the US
"Such energetic and bureaucratic cycles have been typical of Russian history: a major challenge gives rise to a major national response, coercively and collectively organized; the organized response then in turn becomes fossilized and bureaucratically stagnant, leading to a period of decay."

Zbigniew Brzezinski, editor, Dilemmas of Change in Soviet Politics (New York: Columbia University Press, 1969)
