What argument is franklin
d. roosevelt making in this excerpt from his "four freedoms" speech?

He was telling the American public that the United State cannot stay isolated for long.  As Germany had conquered most of Europe, it would only be a matter of time before they focus their attention to America.  He laid down the four freedoms in his speech to tell the audience just how important these freedoms are.  They go beyond party lines and they are what every person values.  If they don’t take action, they would lose all four of them, meaning it would be a matter of time before they are next. Roosevelt wanted to convince them that isolationist policy will not protect them from war and if they truly cherish their freedom, they must be prepare to fight for eventually they will to face the Axis Powers.
