I remember reading a story told by Ezra T. Benson, who served as the Secretary of Agriculture during the Eisenhower administration. The leader of the Soviet Union, Nikita Kruschev (who followed Stalin) was going to visit the U.S. and Benson was ordered by Eisenhower to give Kruschev a tour of some of our agricultural facilities. With great reluctance, Benson agreed to do as requested by the President.
During the tour Kruschev remarked to Secretary Benson that communism would eventually consume democracy. Benson replied that Americans would never accept such a drastic change in their form of government as communism. Kruschev then told Benson that it was already beginning to happen.
He said that Americans were being fed one small bite of communism at a time, and that over the course of several years, Americans will have accepted so many communistic ideals, including a massive and uncontrollable federal government, that one day we would wake up to discover that we are a democracy only in name - that our policies and methods of government will be communist in nature. Kruschev concluded that it will be the slow injection of socialist/communist principles into America - not nuclear missiles - that would destroy our nation.
