What profound impact did the 9/11 incident have on the United States?

You must know that the United States, as the world's hegemon, has not suffered various blows on its own soil for quite some time, and what happened on September 11, 2001 was what the United States suffered after the Pearl Harbor incident. The largest terrorist attack, this incident also led to the outbreak of the war in Afghanistan. All in all, the impact of this terrorist incident is far-reaching, and it even now affects the decision-making of top US officials regarding terrorist organizations.

"9.11" was the first major attack on the United States after the Pearl Harbor incident in World War II. It prompted the United States to launch two wars in Afghanistan and Iraq, completely changing the direction of U.S. foreign strategy. The aftermath of the disaster continues to affect the United States in varying forms.

After the 9/11 incident, the United States not only made unprecedented changes to its national security system, but also made major adjustments to its intelligence work and law enforcement methods. From strengthening airport security to militarizing the police, anti-immigration policies have led to social divisions, and the reconstruction of the intelligence system has led to privacy protection disputes. It has a shadow on the racial conflicts caused by Muslim "Muslim phobia" and even the makeup of the American national character.

Before 9/11, airport security in the United States was no different from that in other parts of the world. In short, formalism far outweighs its substantive role. But immediately after the attack, people reacted, the question was safety! At the time of the incident, passengers on board made contact with the outside world. They reported that the hijackers stabbed the crew members with knives and used toxic chemical sprays such as tear gas and pepper spray. The knives and chemicals must have been listed on the contraband register. How did the terrorists get them on the plane? The answer is the formalistic style of airport security, which makes some security procedures futile.

In order to avoid such a tragedy from happening again, the U.S. Traffic Safety Administration has issued a series of measures to ensure the personal safety of American citizens to the greatest extent.

In general, the 911 incident has had a profound impact on the U.S. government and people of all countries
