This question refers to the "Four Freedoms" speech by President Roosevelt.
Although these questions refer to your own personal experience, and only you can answer them properly, we can still provide some information that might serve as guidance.
The parts that I find strongest about Roosevelt's speech were those in which he discusses his commitment to the betterment of the world. I believe that this should be the most important priority of all leaders. On the other hand, the parts that I found weakest were those where he actually outlines the four freedoms. I do not think that these freedoms are any better than other ones we could come up with. I believe that Roosevelt's evidence was sufficient. He draws on historical examples that make his argument persuasive. Moreover, it was relevant. I also do not believe that he used any fallacious reasoning. Finally, as I have not listened to it, and have only read it, I cannot compare the two experiences.
