"Perception of danger, danger to our institutions, may come slowly or it may come with a rush and a shock as it has to the people of the United States in the past few months. This perception of danger, danger in a
world-wide area-it has come to us clearly and overwhelmingly--we perceive the peril in a world wide arena,
an arena that may become so narrowed that only the Americas will retain the ancient faiths. Some indeed
still hold to the now somewhat obvious delusion that we of the United States can safely permit the United
States to become a lone island, a lone island in a world dominated by the philosophy of force."
Franklin D. Roosevelt, address delivered at Charlottesville, Virginia, June 10, 1940
