Nikita Khrushchev addressed the capitalists in 1956, and said, "We will bury you." He was not referring to the Soviet Union necessarily burying The West. He was saying that communism would bury The West. "History is on our side," he said. Indeed, Khrushchev was right.
The Founding Fathers of the United States were quite aware of history, and in their research they determined that the only government that may stand the test of time, and fight off the advances of oligarchy such as we see in governmental philosophies like communism, is a constitutional republic where self-governance and a central system worked together.
