Final answer:
Roosevelt's speech argued that Americans should be ready to support their allies in the struggle against dictatorship, while providing such support would help maintain U.S. neutrality and protect global freedom and security.
Step-by-step explanation:
In Franklin D. Roosevelt's "Four Freedoms" speech, he is making a couple of key arguments relevant to the time period before the United States entered World War II. Firstly, he is suggesting that while Americans have a history of upholding human rights and opposing injustices, they must now be prepared to extend their fight beyond their borders. Specifically, he emphasizes the importance of supporting allies in their struggle against totalitarian regimes. The second argument is that by assisting democracies and providing aid, particularly to Britain and France in their fight against Germany, America can maintain a strategic position of neutrality while still being involved in promoting global security and freedom.
