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, ... " Bush later apologized for this remark due to the negative connotations the term crusade has to people, e.g. of Muslim faith. The word crusade was not used again. 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."
Henry Benbridge (October 1743 – February 1812) was an early American portrait painter. He was born in Philadelphia, the only child of James and Mary (Clark) Benbridge. When he was seven years old, his mother, who had been left a widow, was married to Thomas Gordon, a wealthy Scot. The boy's artistic talent was encouraged. He made decorative designs for his stepfather's drawing-room which were much admired. When he was fourteen years old he may have watched John Wollaston paint Gordon's portrait. It has been plausibly argued that young Benbridge had instruction from Wollaston, since his earliest known portrait, that of his half-sister Rebecca Gordon, "seems to hark back to Wollaston." When he was 21, Benbridge was sent to Italy, where he studied with Pompeo Batoni and Anton Raphael Mengs. In 1769, on commission from James Boswell, biographer of Dr. Samuel Johnson, he made a portrait of Pasquale Paoli in Corsica which he took to London. It was exhibited (1769) at the Free Society of Artists, and from it three mezzotints were scraped and published with the artist's name signed "Bembridge." Like other young Americans he was encouraged by Benjamin West. He wrote, on December 7, 1769, to his stepfather: "Upon my arrival I waited upon Mr. West who received me with a sort of brotherly affection, as did my cousin, Mrs. West." Impelled, apparently, by a longing to rejoin his family, he left England in 1770, bearing from West the following note of recommendation to Francis Hopkinson: "By Mr. Benbridge you will receive these few lines. You will find him an Ingenous artist and an agreeable Companion. His merit in the art must procure him great incouragement and much esteem. I deare say it will give you great pleasure to have an ingenous artist resident amongst you."

Journalist Yosri Fouda of the Arabic television channel Al Jazeera reported that in April 2002 Khalid Sheikh Mohammed admitted his involvement in the attacks, along with Ramzi bin al-Shibh. The 9/11 Commission Report determined that the animosity towards the United States felt by Mohammed, the principal architect of the 9/11 attacks, stemmed from his "violent disagreement with U.S. foreign policy favoring Israel". Mohammed was also an adviser and financier of the 1993 World Trade Center bombing and the uncle of Ramzi Yousef, the lead bomber in that attack.Mohammed was arrested on March 1, 2003, in Rawalpindi, Pakistan, by Pakistani security officials working with the CIA. He was then held at multiple CIA secret prisons and Guantanamo Bay where he was interrogated and tortured with methods including waterboarding. During U.S. hearings at Guantanamo Bay in March 2007, Mohammed again confessed his responsibility for the attacks, stating he "was responsible for the 9/11 operation from A to Z" and that his statement was not made under duress.
