One document to look at if you want to understand your country is Policy Planning Study 23, written by Kennan for the State Department planning staff in 1948. Here's some of what it says:

we have about 50% of the world's wealth, but only 6.3% of its population....In this situation, we cannot fail to be the object of envy and resentment. Our real task in the coming period is to devise a pattern of relationships which will permit us to maintain this position of disparity.... To do so, we will have to dispense with all sentimentality and day-dreaming; and our attention will have to be concentrated everywhere on our immediate national objectives....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.
