This is part of a radio speech delivered by President Roosevelt in December 1940 (this was the second year in WWII, and the US was still neutral in the conflict).

In the first section of his Four Freedoms Speech, President Franklin Roosevelt attempted to put into historical context the dangers of fascism and the ongoing conflicts overseas to the United States. World War Two was already in full swing in Europe and Asia and it was clear to him and many others that the United States could not stay neutral for much longer. However, there were still many that hoped that the United States could stay out of the conflict.

Roosevelt wanted to make it clear that this situation was something unprecedented in world history. That is why he traced the country's history to illustrate the extreme circumstances that faced the United States.
