In the excerpt from Roosevelt's Executive Order No. 9066, the mode of persuasion used to appeal to the audience is ethos, an appeal based on the speaker's credibility. This is evident because President Roosevelt, as the Commander-in-Chief during World War II, held significant authority and power in the context of issuing executive orders related to national security and military actions. By invoking his authority as the President and Commander-in-Chief, Roosevelt aimed to establish trust and confidence in the necessity and legitimacy of the actions described in the order.
Additionally, the language used in the excerpt emphasizes the directive power granted to the Secretary of War and designated Commanders, highlighting the chain of command and official capacity in which these decisions are made. This further reinforces the credibility of the speaker, President Roosevelt, and the officials empowered to implement the directives outlined in the order.
Overall, by relying on his credibility and authority as the President of the United States, Roosevelt sought to persuade the audience, which in this case would include the military personnel responsible for carrying out the order, government officials, and the general public, of the validity and importance of the actions prescribed in Executive Order No. 9066.
