Final answer:
The attack on Pearl Harbor severely impacted the U.S. navy and prompted the country's full involvement in World War II.
Step-by-step explanation:
The impact of Pearl Harbor on the U.S. navy was significant. The attack by the Japanese on December 7, 1941, destroyed or damaged a significant portion of the U.S. Pacific Fleet, including numerous battleships and aircraft carriers. This attack crippled the navy's ability to effectively respond to future Japanese aggression in the Pacific.
Moreover, the attack on Pearl Harbor propelled the United States into full involvement in World War II. Following the attack, the U.S. declared war on Japan, and subsequently entered into war with the Axis Powers. The attack served as a catalyst for the United States to fully commit its military and industrial resources to the war effort, leading to its eventual victory.
