Question: What is the biggest terrorist attack by the group Bush said the 'war on terror' began with, against the country where native birth is required to be its president?

<P0-S0> 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-S1> 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-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 government of pakistan reacted in the same vein, through its foreign minister khurshid mahmud kasuri, proclaiming that this was an act of terrorism that should be investigated by indian authorities. <P1-S1> kasuri said that the terrorist attack would not halt his trip to india, as he "will be leaving tomorrow for delhi to further the peace process." <P1-S2> he went on to say that "we should hasten the peace process." <P1-S3> in response to the terrorist attack, president pervez musharraf stated "such wanton acts of terrorism will only serve to further strengthen our resolve to attain the mutually desired objective of sustainable peace between the two countries." <P1-S4> musharraf also said that there must be a full indian investigation of the attack. <P1-S5> in regards to the upcoming peace talks, he stated "we will not allow elements which want to sabotage the ongoing peace process to succeed in their nefarious designs." <SEP> <P2-S0> on 7 january 2015, two french muslim extremists attacked the paris headquarters of charlie hebdo and killed thirteen people, and on 9 january, a third terrorist killed four hostages during an attack at a jewish grocery store at porte de vincennes. <P2-S1> on 11 january an estimated 1.5 million people marched in paris–along with international political leaders–to show solidarity against terrorism and in defence of freedom of speech. <P2-S2> ten months later, 13 november 2015, came a series of coordinated terrorist attacks in paris and saint-denis claimed by the 'islamic state' organisation isil ('daesh', isis); 130 people were killed by gunfire and bombs, and more than 350 were injured. <P2-S3> seven of the attackers killed themselves and others by setting off their explosive vests. <P2-S4> on the morning of 18 november three suspected terrorists, including alleged planner of the attacks abdelhamid abaaoud, were killed in a shootout with police in the paris suburb of saint-denis. <P2-S5> president hollande declared france to be in a three-month state of emergency. <SEP> <P3-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. <P3-S1> 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. <P3-S2> 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". <P3-S3> He was then held at multiple CIA secret prisons and Guantanamo Bay where he was interrogated and tortured with methods including waterboarding. <P3-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> <P4-S0> The U.S. Constitution uses but does not define the phrase ``natural born Citizen '', and various opinions have been offered over time regarding its precise meaning. <P4-S1> The consensus of early 21st - century constitutional scholars, together with relevant case law, is that natural - born citizens include, subject to exceptions, those born in the United States. <P4-S2> Many scholars have also concluded that those who meet the legal requirements for U.S. citizenship`` at the moment of birth'', regardless of place of birth, are also natural - born citizens. <P4-S3> Every president to date was either a citizen at the adoption of the Constitution in 1789 or was born in the United States; of these there have been seven that had at least one parent who was not born on U.S. soil.
