What were two purposes of this excerpt from President Wilson's speech?

Read the excerpt from President Woodrow Wilson's Joint Address to Congress Leading to a Declaration of War Against Germany (1917):

We have no quarrel with the German people. We have no feeling towards them but one of sympathy and friendship. It was not upon their impulse that their government acted in entering this war. It was not with their previous knowledge or approval. It was a war determined upon as wars used to be determined upon in the old, unhappy days when peoples were nowhere consulted by their rulers and wars were provoked and waged in the interest of dynasties or of little groups of ambitious men who were accustomed to use their fellow men as pawns and tools.

— President Woodrow Wilson

A. to change the way people viewed civilian populations
B. to convince people that the German government was unrepresentative of its people
C. to prevent discrimination against German-Americans
D. to change the way the German-Americans felt about their ancestors

From the tone of the President Wilson we can see that he is trying to prevent a situation that would make the people of the United States to become discriminatory to Germans.

Also he talked about how the peopel were sometimes unaware of the intentions and actions of the people that ruled them.
