Final answer:
Presidential speeches play a crucial role in shaping public morale and political support. Carter's speech is often viewed negatively for its lack of reassurance, while Roosevelt's speech is celebrated for inspiring confidence during the Great Depression.
Step-by-step explanation:
The question pertains to the effectiveness and impact of presidential speeches in response to crises and their influence on public perception and political landscapes. President Carter's candid speech lacked the usual reassurance expected by the American public and failed to provide a clear plan for addressing national issues, leading to a negative reception and the term "Malaise" speech. In contrast, other leaders like President Roosevelt used speeches to inspire confidence, calling Americans to action against economic challenges and coining the famous phrase, "The only thing we have to fear is fear itself." The diverse reactions to these speeches reflect the complex relationship between presidential rhetoric, public morale, and historical context.
