Question: What is the biggest terrorist attacks by the Islamic terrorist group starting the 'war on terror' as said by Bush against the country declaring war on Mexico in 1846?

<P0-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. <P0-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". <P0-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. <P0-S3> He was then held at multiple CIA secret prisons and Guantanamo Bay where he was interrogated and tortured with methods including waterboarding. <P0-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> <P1-S0> the war on terrorism is a global effort by the governments of several countries (primarily the united states and its principal allies) to neutralize international terrorist groups (primarily islamic extremist terrorist groups, including al-qaeda) and ensure that countries considered by the us and some of its allies to be rogue nations no longer support terrorist activities. <P1-S1> it has been adopted primarily as a response to the september 11, 2001 attacks on the united states. <P1-S2> since 2001, terrorist motivated attacks upon service members have occurred in arkansas and texas. <SEP> <P2-S0> for the united states, article one, section eight of the constitution says ``congress shall have power to... declare war. <P2-S1> ''however, that passage provides no specific format for what form legislation must have in order to be considered a`` declaration of war'' nor does the constitution itself use this term. <P2-S2> in the courts, the united states court of appeals for the first circuit, in doe v. bush, said: ``(t) he text of the october resolution itself spells out justifications for a war and frames itself as an 'authorization' of such a war. <P2-S3> ''in effect saying an authorization suffices for declaration and what some may view as a formal congressional`` declaration of war'' was not required by the constitution. <SEP> <P3-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. <P3-S1> of Muslim faith. <P3-S2> The word crusade was not used again. <P3-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. <P3-S4> It will not end until every terrorist group of global reach has been found, stopped, and defeated." <SEP> <P4-S0> The United States Congress declared war on Mexico on May 13, 1846 after only having a few hours to debate. <P4-S1> Although President José Mariano Paredes's issuance of a manifesto on May 23 is sometimes considered the declaration of war, Mexico officially declared war by Congress on July 7. <P4-S2> After the American invasion of New Mexico, Chihuahua sent 12,000 men led by Colonel Vidal to the border to stop the American military advance into the state. <P4-S3> The Mexican forces being impatient to confront the American forces passed beyond El Paso del Norte about 20 miles (32 km) north along the Rio Grande. <P4-S4> The first battle that Chihuahua fought was the battle of El Bracito; the Mexican forces consisting of 500 cavalry and 70 infantry confronted a force of 1,100–1,200 Americans on December 25, 1846. <P4-S5> The battle ended badly by the Mexican forces that were then forced to retreat back into the state of Chihuahua. <P4-S6> By December 27, 1846, the American forces occupied El Paso Del Norte. <P4-S7> General Doniphan maintained camp in El Paso Del Norte awaiting supplies and artillery which he received in February 1847.
