Question: What were the largest terror attacks against the country with the most powerful economy by the group that Bush said the 'war on terror' begins with?

<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> 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-S2> of Muslim faith. <P0-S3> The word crusade was not used again. <P0-S4> It will not end until every terrorist group of global reach has been found, stopped, and defeated." <SEP> <P1-S0> 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". <P1-S1> 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. <P1-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. <P1-S3> He was then held at multiple CIA secret prisons and Guantanamo Bay where he was interrogated and tortured with methods including waterboarding. <P1-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. <SEP> <P2-S0> petroleum was discovered on 3 march 1938 and followed up by several other finds in the eastern province. <P2-S1> saudi arabia has since become the world's second largest oil producer (behind the us) and the world's largest oil exporter, controlling the world's second largest oil reserves and the sixth largest gas reserves. <P2-S2> the kingdom is categorized as a world bank high-income economy with a high human development index and is the only arab country to be part of the g-20 major economies. <P2-S3> the state has attracted criticism for a variety of reasons including: its archaic treatment of women, its excessive and often extrajudicial use of capital punishment, state-sponsored discrimination against religious minorities and atheists, its role in the yemeni civil war, sponsorship of islamic terrorists, and its strict interpretation of sharia law. <P2-S4> the kingdom has the world's third-highest military expenditure and, according to sipri, was the world's second largest arms importer from 2010 to 2014. saudi arabia is considered a regional and middle power. <P2-S5> in addition to the gcc, it is an active member of the organisation of islamic cooperation and opec. <SEP> <P3-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. <P3-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. <P3-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> <P4-S0> The United States is the world's largest economy with a GDP of approximately $19.39 trillion, notably due to high average incomes, a large population, capital investment, moderate unemployment, high consumer spending, a relatively young population, and technological innovation. <P4-S1> Tuvalu is the world's smallest national economy, with a GDP of about $32 million, because of its very small population, a lack of natural resources, reliance on foreign aid, negligible capital investment, demographic problems, and low average incomes.
