Final answer:
Roosevelt's approach to creating a world with freedom from fear involved a significant global reduction in armaments, ensuring no country could engage in aggressive acts. His Four Freedoms Speech and subsequent Atlantic Charter aimed to emphasize essential freedoms and international cooperation for a peaceful post-war world.
Step-by-step explanation:
President Franklin D. Roosevelt suggested that to create a world with freedom from fear, there must be a significant reduction in armaments globally. This reduction in armaments should be to such an extent that no nation would be capable of committing acts of physical aggression against its neighbors. Roosevelt's vision, presented in his Four Freedoms Speech, was part of his broader effort to encourage a post-war world grounded in these four essential human freedoms: freedom of speech, freedom of worship, freedom from want, and freedom from fear. By signing the Atlantic Charter with Winston Churchill, Roosevelt underlined the need for self-determination, economic cooperation, and political cooperation to safeguard these freedoms.
In addressing his nation during challenging times, Roosevelt's rhetoric often focused on inspiring confidence and cooperation among the American people, specifically promoting the understanding and support of policies that would be central to recovery and stability. His adept use of language to galvanize public support was key in rallying the nation to face and overcome the hardships of the era.
