<u>Explanation:</u>
Roosevelt’s speech is even today motivating and inspiring lives around the world. His famous words, "<em>The only thing we have to fear is fear itself – nameless, unreasoning, unjustified terror that paralyses needed efforts to convert retreat into advance.</em>" With his speech he hoped to convince the people of America that if they fear today, fear will overpower them. But if they fight today then they can themselves secure their own future. When Roosevelt came into the picture, more than half of America was struggling with unemployment. His speeches were promises that people needed.
