Within a month, the forces of a coalition led by the United States entered Afghanistan, which had been sheltering Osama bin Laden, suspected mastermind of the September 11 attacks. By December, the Taliban had been removed as rulers of Kabul, although a long and ongoing reconstruction would follow, severely hampered by ongoing turmoil and violence within the country.

Document 10: War on Terror: On 16 September 2001, at Camp David, President George W. Bush used the phrase war on terrorism in an unscripted and controversial comment when he said, "This crusade – this war on terrorism – is going to take a while, ...

On 20 September 2001, during a televised address to a joint session of congress, Bush stated that, "(o)ur 'war on terror' begins with al-Qaeda, but it does not end there. It will not end until every terrorist group of global reach has been found, stopped, and defeated."
Document 11: War on Terror: In 2002, the Musharraf-led government took a firm stand against the jihadi organizations and groups promoting extremism, and arrested Maulana Masood Azhar, head of the Jaish-e-Mohammed, and Hafiz Muhammad Saeed, chief of the Lashkar-e-Taiba, and took dozens of activists into custody. An official ban was imposed on the groups on 12 January.

Zubaydah is said to have been a high-ranking al-Qaeda official with the title of operations chief and in charge of running al-Qaeda training camps. Other prominent al-Qaeda members were arrested in the following two years, namely Ramzi bin al-Shibh, who is known to have been a financial backer of al-Qaeda operations, and Khalid Sheikh Mohammed, who at the time of his capture was the third highest-ranking official in al-Qaeda and had been directly in charge of the planning for the 11 September attacks.
Document 12: War on Terror: Because the actions involved in the "war on terrorism" are diffuse, and the criteria for inclusion are unclear, political theorist Richard Jackson has argued that "the 'war on terrorism' therefore, is simultaneously a set of actual practices—wars, covert operations, agencies, and institutions—and an accompanying series of assumptions, beliefs, justifications, and narratives—it is an entire language or discourse." Jackson cites among many examples a statement by John Ashcroft that "the attacks of September 11 drew a bright line of demarcation between the civil and the savage". Administration officials also described "terrorists" as hateful, treacherous, barbarous, mad, twisted, perverted, without faith, parasitical, inhuman, and, most commonly, evil. Americans, in contrast, were described as brave, loving, generous, strong, resourceful, heroic, and respectful of human rights.

Francis Hopkinson, a signer of the Declaration of Independence, was a notable composer of the period. One of his compositions, "My Days Have Been So Wondrous Free", is well-remembered as the first art song from the United States (though this is disputed); it is, however, lacking in originality and innovation to set it apart from European compositions.
