The attack on Pearl Harbor on December 7, 1941, was a pivotal moment in American history, marking the United States' entry into World War II. The surprise attack by Japanese forces resulted in significant loss of life and damage to the U.S. naval fleet stationed at Pearl Harbor, Hawaii. This event not only reshaped the course of the war, but also had a profound impact on the American psyche and its role in world affairs. In this essay, we will analyze the events leading up to the attack on Pearl Harbor and its aftermath through the use of a document-based questioning (DBQ) approach. By examining primary source documents and historical context, we will explore the complex factors that led to the attack and assess its consequences. This investigation will shed light on the debates and theories surrounding the attack, providing a better understanding of its significance in American history. Ultimately, this essay aims to demonstrate how the attack on Pearl Harbor was a defining moment that changed the course of World War II and had lasting implications for the United States and the world. The primary contributing factor to the attack on Pearl Harbor was the growing tension between the United States and Japan in the years leading up to the event. Japanese expansionist policies in Asia, particularly in China, posed a direct threat to American interests in the region. This situation was exacerbated by economic sanctions imposed by the United States on Japan in response to its aggressive actions. As Document A shows, the Japanese government viewed these sanctions as a threat to its national security and sought to ensure access to vital resources by expanding its territorial control. This growing hostility and competition for power in the Pacific has set the stage for potential conflict between the two nations. The attack on Pearl Harbor can therefore be seen as the culmination of escalating tensions and rivalry between the United States and Japan. The consequences of this attack, as we will explore in the following paragraphs, were far-reaching and had a profound impact on the course of the war and the global balance of power.

This failure to accurately assess the threat posed by Japan and properly prepare for a potential attack left American forces vulnerable and unprepared on the day of the assault. The consequences of this intelligence failure were catastrophic, resulting in the loss of many American lives and the destruction of a significant portion of the Pacific Fleet. The attack on Pearl Harbor thus exposed critical weaknesses in United States intelligence and military preparedness, prompting a reassessment of its national security strategies and policies. This event served as a wake-up call for the United States, leading it to refocus on improving its intelligence capabilities and military preparedness for future threats. Furthermore, the attack on Pearl Harbor had a profound impact on the American psyche and its perception of its.
