John F. Kennedy on Communism

“Communism has sometimes succeeded as a scavenger, but never as a leader. It has never come to power in a country that was not disrupted by war or corruption, or both.”

“The Communists are determined to destroy us, and regardless of what hand of friendship we may hold out or what arguments we may put up, the only thing that will make that decisive difference is the strength of the United States.”

“There are many people in the world who really don't understand, or say they don't, what is the great issue between the free world and the Communist world. Let them come to Berlin. There are some who say that communism is the wave of the future. Let them come to Berlin. And there are some who say in Europe and elsewhere we can work with the Communists. Let them come to Berlin. And there are even a few who say that it is true that communism is an evil system, but it permits us to make economic progress. Lass' sie nach Berlin kommen. Let them come to Berlin.”
