BU faculty reflect on how that day’s events have reshaped our lives over the last 20 years

Saturday, September 11, 2021, marks the 20th anniversary of 9/11, the largest terrorist attack in history. On that Tuesday morning, 19 al-Qaeda terrorists hijacked four American commercial flights destined for the West Coast and intentionally crashed them. Two planes—American Airlines Flight 11 and United Airlines Flight 175—departed from Boston and Flight 11 struck New York City’s World Trade Center North Tower at 8:46 am and Flight 175 the South Tower at 9:03 am, resulting in the collapse of both towers. A third plane, American Airlines Flight 77, leaving from Dulles International Airport in Virginia, crashed into the Pentagon at 9:37 am, and the final plane, United Airlines Flight 93, departing from Newark, N.J., crashed in a field in Shanksville, Pa., at 10:03 am, after passengers stormed the co*ckpit and tried to subdue the hijackers.
In the space of less than 90 minutes on a late summer morning, the world changed. Nearly 3,000 people were killed that day and the United States soon found itself mired in what would become the longest war in its history, a war that cost an estimated $8 trillion. The events of 9/11 not only reshaped the global response to terrorism, but raised new and troubling questions about security, privacy, and treatment of prisoners. It reshaped US immigration policies and led to a surge in discrimination, racial profiling, and hate crimes.
In observance of the anniversary, BU Today reached out to faculty across Boston University—experts in international relations, international security, immigration law, global health, terrorism, and ethics—and asked each to address this question: “How has the world changed as a result of 9/11?”

This was a very sad moment in time but we need to remember the people that sacrificed themselves to save us and the people that died during this event. It was sad but at least it brought us closer together. I wonder what the world would be like if 9/11 never happened?..

9/11 is tragic and it will always be remembered though I have to say that saying 9/11 changed the word is quite an overstatement. More like how it changes America in certain ways and the ones responsible for it but saying something like what you said makes it sound like it was Armageddon or something.

Whether or not those of us in other countries like it, for the last several decades and certainly still in the current time, when something changes the USA in significant ways that impact policy, legislation, education, the economy, health care, etc. (not to mention the ways in which public opinion drives the American political machine), the US’s presence on the international stage means those changes ripple outward through their foreign policy, treatment of both residents/citizens of the USA and local people where the USA has a military, economic and/or other presence around the world.
The complex web of international agreements, alliances, organizational memberships, and financial interdependency means that events that happen locally often have both direct and indirect implications, short and long term, around the world, for individuals and for entire segments of society.
As for the direct results of 20 years of military response to 9/11 on civilians in Iraq and Afghanistan, it certainly changed their world.

I have to say this is most definitely a U.S. American write up. Saying the word is an overstatement in many ways. It would be more better if you were to specifically point out you mean the US and those others involved with the attacks. Overall if we are going to be completely factual “people/individuals” are the ones who change things depending on whatever. The world changes every day since the start of time.

While I agree with your first point, I would say that the attacks did in fact change the world. At the very least, they changed the way airline security is done everywhere.

I believe that the people, who sacrificed their lives in flight 93, the one that crashed in Pennsylvania, resonated the most with me, as it could have gone anywhere, and they sacrificed themselves to save more. I am deeply sorry for all losses, but I hope we remember this crucial moment in history to learn from our mistakes in global affairs, but also honor those who sacrificed themselves in all the attacks.
