I address you, the Members of the Seventy-seventh Congress, at a moment unprecedented in the history of the Union. I use the word "unprecedented," because at no previous time has American security been as seriously threatened from without as it is today. Since the permanent formation of our Government under the Constitution, in 1789, most of the periods of crisis in our history have related to our domestic affairs. Fortunately, only one of these--the four-year War Between the States--ever threatened our national unity. Today, thank God, one hundred and thirty million Americans, in forty-eight States, have forgotten points of the compass in our national unity. It is true that prior to 1914 the United States often had been disturbed by events in other Continents. We had even engaged in two wars with European nations and in a number of undeclared wars in the West Indies, in the Mediterranean and in the Pacific for the maintenance of American rights and for the principles of peaceful commerce. But in no case had a serious threat been raised against our national safety or our continued independence. What I seek to convey is the historic truth that the United States as a nation has at all times maintained clear, definite opposition, to any attempt to lock us in behind an ancient Chinese wall while the procession of civilization went past. Today, thinking of our children and of their children, we oppose enforced isolation for ourselves or for any other part of the Americas.

Use the speech by President Franklin Roosevelt to answer the question. How does President Roosevelt appeal to emotion in the opening to his speech? Why or why not is the opening paragraph valid and sound? Record your response in 3–4 sentences.

President Roosevelt appeals to emotion in the opening of his speech by using phrases like "at a moment unprecedented in the history of the Union" and "thank God, one hundred and thirty million Americans...have forgotten points of the compass in our national unity." These phrases evoke a sense of urgency and patriotism, appealing to the emotions of the American people. The opening paragraph is valid and sound because it effectively sets the tone for the rest of the speech by highlighting the gravity of the situation and emphasizing the importance of unity and vigilance in the face of external threats.
