Discover President Roosevelt’s reaction to the attack on Pearl Harbor.

Transcript: 

Yesterday, December 7, 1941—a date which will live in infamy—the United States of America was suddenly and deliberately attacked by naval and air forces of the Empire of Japan. 

The United States was at peace with that Nation and, at the solicitation of Japan, was still in conversation with its Government and its Emperor looking toward the maintenance of peace in the Pacific. Indeed, one hour after Japanese air squadrons had commenced bombing in the American Island of Oahu, the Japanese Ambassador to the United States and his colleague delivered to our Secretary of State a formal reply to a recent American message. And while this reply stated that it seemed useless to continue the existing diplomatic negotiations, it contained no threat or hint of war or of armed attack. 

It will be recorded that the distance of Hawaii from Japan makes it obvious that the attack was deliberately planned many days or even weeks ago. During the intervening time the Japanese Government has deliberately sought to deceive the United States by false statements and expressions of hope for continued peace. 

The attack yesterday on the Hawaiian Islands has caused severe damage to American naval and military forces. I regret to tell you that very many American lives have been lost. In addition American ships have been reported torpedoed on the high seas between San Francisco and Honolulu. 

Yesterday the Japanese Government also launched an attack against Malaya. 

Last night Japanese forces attacked Hong Kong. 

Last night Japanese forces attacked Guam. 

Last night Japanese forces attacked the Philippine Islands. 

Last night the Japanese attacked Wake Island. And this morning the Japanese attacked Midway Island.

Use this additional sourcing information to further contextualize the source in order to deepen students’ analysis and evaluation. 

Summary

This is the first part of the famous speech from President Roosevelt to a joint session of Congress the day after the Pearl Harbor attack. In the speech, he informs the public about the bombing. 

Purpose

The purpose of the speech was to persuade both Congress and the American people that war was the only way to respond to the Japanese attack. 

Intended Audience

The audience was Congress, the American people listening on the radio, and the broader international audience of Japanese leaders and U.S. allies. 

Source Considerations

Roosevelt had long wanted the United States to become involved in World War II, and the bombing of Pearl Harbor was the tipping point. The speech was aired live on the radio. Roosevelt concludes the speech by asking Congress to declare war. They did so 30 minutes later. 

Scaffolding and Differentiation: Reading Comprehension Support

Genre    

The power of this speech, combined with the shock of the attack, persuaded Congress to quickly declare war, and it won the assent of the American populace. Ask students to reflect on the rhetoric Roosevelt uses. 

Vocabulary  

Vocabulary that may challenge students includes infamy and solicitation. Be sure students are aware that Guam, the Philippines, Wake Island, Midway Island, and Hawaii were U.S. territories at the time of World War II. 

Analyze and Discuss

To extend discussions, consider asking the following questions.

  • What are two quotes from the source that reflect the author’s perspective on the bombing of Pearl Harbor?
    • (Answers will vary but may include “Yesterday, December 7, 1941—a date which will live in infamy—the United States of America was suddenly and deliberately attacked” or “I regret to tell you that very many American lives have been lost.”) 
  • How would you summarize each of these quotes in your own words?
    • (Answers will vary but may include “The decision to cover some candidates more than others is often driven by economics, as outlets want to publish stories they think will drive traffic;” “many publications differentiate themselves by shifting from news to analysis;” or “Thanks to data-journalism tools that make verification fast and accurate, fact-checking has become a major part of the election media cycle.”)
