What audience does Roosevelt address

The audience that Roosevelt addresses is the people living in that area. In the excerpt from Franklin D. Roosevelt’s "Four Freedoms" speech, he suggests that going to war will result in a peaceful political system is by the sentence:

This nation has placed its destiny in the hands and heads and hearts of its millions of free men and women; and its faith in freedom under the guidance of God. Freedom means the supremacy of human rights everywhere. Our support goes to those who struggle to gain those rights or keep them. Our strength is our unity of purpose. To that high concept there can be no end save victory.
