Question: What were the biggest terrorist attacks by the group Bush declared war against in the country with the world's largest economy in 2014?

<P0-S0> 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. <P0-S1> of Muslim faith. <P0-S2> The word crusade was not used again. <P0-S3> 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. <P0-S4> It will not end until every terrorist group of global reach has been found, stopped, and defeated." <SEP> <P1-S0> these attacks resonated with conservative muslims and the problem did not go away with saddam's defeat either, since american troops remained stationed in the kingdom, and a de facto cooperation with the palestinian-israeli peace process developed. <P1-S1> saudi arabia attempted to compensate for its loss of prestige among these groups by repressing those domestic islamists who attacked it (bin laden being a prime example), and increasing aid to islamic groups (islamist madrassas around the world and even aiding some violent islamist groups) that did not, but its pre-war influence on behalf of moderation was greatly reduced. <P1-S2> one result of this was a campaign of attacks on government officials and tourists in egypt, a bloody civil war in algeria and osama bin laden's terror attacks climaxing in the 9/11 attack. <SEP> <P2-S0> Although the rankings of national economies have changed considerably over time, the United States has maintained its top position since the Gilded Age, a time period in which its economy saw rapid expansion, surpassing the British Empire and Qing dynasty in aggregate output. <P2-S1> Since China's transition to a market - based economy through privatisation and deregulation, the country has seen its ranking increase from ninth in 1978 to second to only the United States in 2016 as economic growth accelerated and its share of global nominal GDP surged from 2% in 1980 to 15% in 2016. <P2-S2> India has also experienced a similar economic boom since the implementation of economic liberalisation in the early 1990s. <P2-S3> When supranational entities are included, the European Union is the second largest economy in the world. <P2-S4> It was the largest from 2004, when ten countries joined the union, to 2014, after which it was surpassed by the United States. <SEP> <P3-S0> other critics, such as francis fukuyama, note that "terrorism" is not an enemy, but a tactic; calling it a "war on terror", obscures differences between conflicts such as anti-occupation insurgents and international mujahideen. <P3-S1> with a military presence in iraq and afghanistan and its associated collateral damage shirley williams maintains this increases resentment and terrorist threats against the west. <P3-S2> there is also perceived u.s. hypocrisy, media-induced hysteria, and that differences in foreign and security policy have damaged america's image in most of the world. <SEP> <P4-S0> 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. <P4-S1> 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". <P4-S2> 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. <P4-S3> He was then held at multiple CIA secret prisons and Guantanamo Bay where he was interrogated and tortured with methods including waterboarding. <P4-S4> 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.
