September 11 should be remembered because it marks the day of the deadliest terrorist attacks in U.S. history, when four commercial planes were hijacked and used as weapons, killing nearly 3,000 innocent people. It is a day to honor and remember the victims, the bravery of first responders, and the resilience and unity of the American people in the face of evil. It also serves as a solemn reminder of the need for vigilance against terrorism and the value of national unity and patriotism. Patriot Day on September 11 is officially designated to commemorate the attacks and to reflect on the enduring impact on the nation's history and values.
