Indeed, Wilson had sent a series of messages to Congress in order to persuade them to declare War on Germany and the Central Powers. It is a clear utilization of Pathos as he dismisses the idea that the war is being waged due to conflicting European imperial interests but due to the “savagery” of Germans.
