What event in recent history is compared to the pearl harbor attack?

The September 11, 2001, terrorist attacks are often compared to the Pearl Harbor attack due to their suddenness and the profound impact they had on the United States. Both events resulted in significant loss of life and prompted the U.S. to engage in military actions and re-evaluate its national security policies. Just as Pearl Harbor galvanized the nation to enter World War II, 9/11 led to the War on Terror and major shifts in foreign and domestic policy.
