Final answer:
Roosevelt used persuasive appeals like ethos and pathos in his fireside chats to build trust and support for his New Deal policies, and fulfilled campaign promises by expanding government and presidential roles and adopting a nuanced foreign policy.
Step-by-step explanation:
In his speeches and public communications, Franklin D. Roosevelt used persuasive appeals to convey messages of reassurance and to push his policy agenda. His use of the fireside chats was specifically aimed at creating a sense of intimacy with the American people, addressing them as equals and tapping into the ethos of the presidency to build trust. Roosevelt was keen on using pathos to evoke feelings of unity and determination during challenging times. By employing clear and accessible language, he was able to simplify complex issues and directly explain the benefits of his New Deal policies. This direct communication style was crucial in shaping public opinion and garnering the support needed to pass legislation.
The purpose of these persuasive appeals was to expand both the government and the presidency beyond their conventional roles, as well as to fulfill his campaign promises. Roosevelt's response to foreign policy varied in regions such as Latin America and Asia, employing different methods where necessary, demonstrating a nuanced and strategic approach to diplomacy.
