Review Questions

  • How did the attack on Pearl Harbor change public opinion in the United States regarding involvement in World War II?
    • Before the attack on Pearl Harbor, many Americans supported isolationism and were reluctant to become involved in international conflicts. The surprise attack shifted public opinion dramatically, as it united the nation in outrage and a desire for retaliation. The attack was seen as a direct threat to national security, prompting widespread support for entering World War II and mobilizing resources for war efforts.
  • Discuss the immediate military and strategic consequences of the Pearl Harbor attack for both Japan and the United States.
    • The immediate military consequence of the Pearl Harbor attack was that it severely damaged the U.S. Pacific Fleet, but it did not destroy key assets like aircraft carriers that were not present during the attack. For Japan, while they achieved tactical success by crippling American naval power temporarily, they also awakened a sleeping giantโ€”prompting a determined response from the United States. Strategically, it shifted U.S. military focus from defensive operations to aggressive warfare against Japan and solidified alliances with other Allied powers.

    • The attack on Pearl Harbor had profound long-term implications for U.S. foreign policy after World War II. It marked a shift from isolationism to a more interventionist stance, as the U.S. took an active role in global affairs during the Cold War. The need for military readiness became paramount, leading to significant defense spending and alliances like NATO. Additionally, Pearl Harbor set a precedent for intelligence failures that prompted reforms within U.S. military and intelligence agencies to prevent similar surprises in the future.
