George F. Kennan said this quote

Were the Soviet Union to sink tomorrow under the waters of the ocean, the American military-industrial establishment would have to go on, substantially unchanged, until some other adversary could be invented. Anything else would be an unacceptable shock to the American economy.

~ George F. Kennan

We should cease to talk about vague and unreal objectives such as human rights, the raising of the living standards, and democratization. The day is not far off when we are going to have to deal in straight power concepts. The less we are then hampered by idealistic slogans, the better.

~ George F. Kennan

Heroism is endurance for one moment more.

~ George F. Kennan

The very concept of history implies the scholar and the reader. Without a generation of civilized people to study history, to preserve its records, to absorb its lessons and relate them to its own problems, history, too, would lose its meaning.

~ George F. Kennan
