The pretense continued over the generations, helped by all-embracing symbols, physical or verbal: the flag, patriotism, democracy, national interest, national defense, national security. The slogans were dug into the earth of American culture like a circle of covered wagons on the western plain, from inside of which the white, slightly privileged American could shoot to kill the enemy outside--Indians or blacks or foreigners or other whites too wretched to be allowed inside the circle. The managers of the caravan watched at a safe distance, and when the battle was over and the field strewn with dead on both sides, they would take over the land, and prepare another expedition, for another territory.
