September 11, 2001

Figure 2. The World Trade Centers billow smoke after being hit by Boeing 747 airplanes. The first plane to hit its target was American Airlines Flight 11. It was crashed into the North Tower of the World Trade Center complex in Lower Manhattan at 8:46 am. Seventeen minutes later, at 9:03 am, the World Trade Center’s South Tower was hit by United Airlines Flight 175. Both 110-story towers collapsed within an hour and forty-two minutes, leading to the collapse of the other World Trade Center structures including 7 World Trade Center, and significantly damaging surrounding buildings.

Shortly after takeoff on the morning of September 11, 2001, teams of hijackers from the Islamist terrorist group al-Qaeda seized control of four American airliners. Two of the airplanes were flown into the twin towers of the World Trade Center in Lower Manhattan. Morning news programs that were filming the moments after the first impact, then assumed to be an accident, captured and aired live footage of the second plane, as it barreled into the other tower in a flash of fire and smoke. Less than two hours later, the heat from the crash and the explosion of jet fuel caused the upper floors of both buildings to collapse onto the lower floors, reducing both towers to smoldering rubble. The passengers and crew on both planes, as well as 2,606 people in the two buildings, all died, including 343 New York City firefighters who rushed in to save victims shortly before the towers collapsed.

The third hijacked plane was flown into the Pentagon building in northern Virginia, just outside Washington, DC, killing everyone on board and 125 people on the ground. The fourth plane, also heading towards Washington, crashed in a field near Shanksville, Pennsylvania, when passengers, aware of the other attacks, attempted to storm the cockpit and disarm the hijackers. Everyone on board was killed.

Al-Qaeda

American intelligence agencies quickly identified the radical Islamic militant group al-Qaeda, led by the wealthy Saudi Osama bin Laden, as the perpetrators of the attack. Sheltered in Afghanistan by the Taliban, the country’s Islamic government, al-Qaeda was responsible for a 1993 bombing of the World Trade Center and a string of attacks at U.S. embassies and military bases across the world. Bin Laden’s Islamic radicalism and his anti-American aggression attracted supporters across the region and, by 2001, al-Qaeda was active in over sixty countries.

Three days later, Congress issued a joint resolution authorizing the president to use all means necessary against the individuals, organizations, or nations involved in the attacks. On September 20, in an address to a joint session of Congress, Bush declared war on terrorism, blamed al-Qaeda leader Osama bin Laden for the attacks, and demanded that the radical Islamic fundamentalists who ruled Afghanistan, the Taliban, turn bin Laden over or face attack by the United States.

Although in his presidential campaign Bush had denounced foreign nation-building, he populated his administration with neoconservatives, firm believers in the expansion of American democracy and American interests abroad. Bush advanced what was sometimes called the Bush Doctrine, a policy in which the United States would have the right to unilaterally and preemptively make war on any regime or terrorist organization that posed a threat to the United States or to U.S. citizens. It would lead the United States into protracted conflicts in Afghanistan and Iraq and entangle the United States in nations across the world. Journalist Dexter Filkins called it a Forever War, a perpetual conflict waged against an amorphous and undefeatable enemy. The geopolitical realities of the twenty-first-century world were forever transformed.

International Response

World leaders and millions of their citizens expressed support for the United States and condemned the deadly attacks. Russian president Vladimir Putin characterized them as a bold challenge to humanity itself. German chancellor Gerhard Schroder said the events of that day were “not only attacks on the people in the United States, our friends in America, but also against the entire civilized world, against our own freedom, against our own values, values which we share with the American people.” Yasser Arafat, chairman of the Palestinian Liberation Organization and a veteran of several bloody struggles against Israel, was dumbfounded by the news and announced to reporters in Gaza, “We completely condemn this very dangerous attack, and I convey my condolences to the American people, to the American president and to the American administration.
