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?

full_context: Document 1: 2004 United States presidential election: Just eight months into his presidency, the terrorist attacks of September 11, 2001 suddenly transformed Bush into a wartime president. Bush's approval ratings surged to near 90%. Within a month, the forces of a coalition led by the United States entered Afghanistan, which had been sheltering Osama bin Laden, suspected mastermind of the September 11 attacks. By December, the Taliban had been removed as rulers of Kabul, although a long and ongoing reconstruction would follow, severely hampered by ongoing turmoil and violence within the country.
Document 2: Military history of the United States: 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. It has been adopted primarily as a response to the September 11, 2001 attacks on the United States. Since 2001, terrorist motivated attacks upon service members have occurred in Arkansas and Texas.
Document 3: Chihuahua (state): President Juárez once again based his government in the state of Chihuahua and it served as the center for the resistance against the French invasion throughout Mexico. On March 25, 1866, a battle ensued in the Plaza de Armas in the center of Chihuahua City between the French imperial forces that were guarding the plaza and the Republican forces led by General Terrazas. Being completely caught off guard, the French imperial forces sought refuge by bunkering themselves in the Cathedral of the Holy Cross, Our Lady of Regla, and St Fancis of Assisi and made it almost impossible to penetrate their defenses. General Terrazas then decided to fire a heavy artillery barrage with 8 kg cannonballs. The first cannon fired hit a bell in the tower of the church, instantly breaking it in half; soon after, 200 men of the imperial army forces surrendered. The republican forces had recovered control over the state capital. The bell in the church was declared a historical monument and can be seen today in the Cathedral. By April 1866, the state government had established a vital trading route from Chihuahua City to San Antonio, Texas; the government began to replenish their supplies and reinforce their fight against the Imperial forces.
Document 4: Chihuahua (state): The Treaty of Guadalupe Hidalgo, signed on February 2, 1848, by American diplomat Nicholas Trist and Mexican plenipotentiary representatives Luis G. Cuevas, Bernardo Couto, and Miguel Atristain, ended the war, gave the U.S. undisputed control of Texas, and established the U.S.–Mexican border of the Rio Grande. As news of peace negotiations reached the state, new call to arms began to flare among the people of the state. But as the Mexican officials in Chihuahua heard that General Price was heading back to Mexico with a large force comprising several companies of infantry and three companies of cavalry and one division of light artillery from Santa Fe on February 8, 1848, Ángel Trías sent a message to Sacramento Pass to ask for succession of the area as they understood the war had concluded. General Price, misunderstanding this as a deception by the Mexican forces, continued to advance towards the state capital. On March 16, 1848 Price began negotiations with Ángel Trías, but the Mexican leader responded with an ultimatum to General Price. The American forces engaged with the Mexican forces near Santa Cruz de los Rosales on March 16, 1848. The Battle of Santa Cruz de los Rosales was the last battle of the Mexican–American War and it occurred after the peace treaty was signed. The American forces maintained control over the state capital for three months after the confirmation of the peace treaty. The American presence served to delay the possible succession of the state which had been discussed at the end of 1847, and the state remained under United States occupation until May 22, 1848.
Document 5: War on Terror: In 2002, the Musharraf-led government took a firm stand against the jihadi organizations and groups promoting extremism, and arrested Maulana Masood Azhar, head of the Jaish-e-Mohammed, and Hafiz Muhammad Saeed, chief of the Lashkar-e-Taiba, and took dozens of activists into custody. An official ban was imposed on the groups on 12 January. Later that year, the Saudi born Zayn al-Abidn Muhammed Hasayn Abu Zubaydah was arrested by Pakistani officials during a series of joint U.S.-Pakistan raids. Zubaydah is said to have been a high-ranking al-Qaeda official with the title of operations chief and in charge of running al-Qaeda training camps. Other prominent al-Qaeda members were arrested in the following two years, namely Ramzi bin al-Shibh, who is known to have been a financial backer of al-Qaeda operations, and Khalid Sheikh Mohammed, who at the time of his capture was the third highest-ranking official in al-Qaeda and had been directly in charge of the planning for the 11 September attacks.
Document 6: Mamdouh Habib: Arrested after the 9/11 attacks in 2001 during a trip to Pakistan and Afghanistan, Habib was interrogated there by Pakistani and United States CIA agents before being shipped by extraordinary rendition to Egypt, where he was held for six months and interrogated more under torture. The CIA transferred him back to a black site in Afghanistan for more torture and interrogation, then to US military custody. In 2002 Habib was transferred to the Guantanamo Bay detention camp. He continued to be held without charges and suffered coercive interrogation.
Document 7: War on Terror: 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."
Document 8: Mexican–American War: The Mexican -- American War, also known as the Mexican War and in Mexico the American intervention in Mexico, was an armed conflict between the United States of America and the United Mexican States (Mexico) from 1846 to 1848. It followed in the wake of the 1845 American annexation of the independent Republic of Texas, which Mexico still considered its northeastern province and a part of its territory after its de facto secession in the 1836 Texas Revolution a decade earlier.
Document 9: Chihuahua (state): The United States Congress declared war on Mexico on May 13, 1846 after only having a few hours to debate. 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. 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. 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. 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. The battle ended badly by the Mexican forces that were then forced to retreat back into the state of Chihuahua. By December 27, 1846, the American forces occupied El Paso Del Norte. General Doniphan maintained camp in El Paso Del Norte awaiting supplies and artillery which he received in February 1847.
Document 10: September 11 attacks: 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.
Document 11: United States–Yemen relations: In the years after the September 11, 2001 attack on the World Trade Center in New York City, Yemen became a key site for U.S. intelligence gathering and drone attacks on Al-Qaeda. According to the 2012 U.S. Global Leadership Report, 18% of Yemenis approved of U.S. leadership, with 59% disapproving and 23% uncertain. According to a February 2015 report from the Congressional Research Service, U.S. officials considered Al-Qaeda in the Arab Peninsula the Al-Qaeda affiliate "most likely to attempt transnational attacks against the United States."
Document 12: Chihuahua (state): On February 8, 1847, Doniphan continued his march with 924 men mostly from Missouri; he accompanied a train of 315 wagons of a large commercial caravan heading to the state capital. Meanwhile, the Mexican forces in the state had time to prepare a defense against the Americans. About 20 miles (32 km) north of the capital where two mountain ranges join from east to west is the only pass into the capital; known as Sacramento Pass, this point is now part of present-day Chihuahua City. The Battle of Sacramento was the most important battle fought in the state of Chihuahua because it was the sole defense for the state capital. The battle ended quickly because of some devastating defensive errors from the Mexican forces and the ingenious strategic moves by the American forces. After their loss at the Battle of Sacramento, the remaining Mexican soldiers retreated south, leaving the city to American occupation. Almost 300 Mexicans were killed in the battle, as well as almost 300 wounded. The Americans also confiscated large amounts of Mexican supplies and took 400 Mexican soldiers prisoners of war. American forces maintained an occupation of the state capital for the rest of the Mexican–American War.
Document 13: War on Terror: On 12 January 2002, Musharraf gave a speech against Islamic extremism. He unequivocally condemned all acts of terrorism and pledged to combat Islamic extremism and lawlessness within Pakistan itself. He stated that his government was committed to rooting out extremism and made it clear that the banned militant organizations would not be allowed to resurface under any new name. He said, "the recent decision to ban extremist groups promoting militancy was taken in the national interest after thorough consultations. It was not taken under any foreign influence".
Document 14: War on Terror: Because the actions involved in the "war on terrorism" are diffuse, and the criteria for inclusion are unclear, political theorist Richard Jackson has argued that "the 'war on terrorism' therefore, is simultaneously a set of actual practices—wars, covert operations, agencies, and institutions—and an accompanying series of assumptions, beliefs, justifications, and narratives—it is an entire language or discourse." Jackson cites among many examples a statement by John Ashcroft that "the attacks of September 11 drew a bright line of demarcation between the civil and the savage". Administration officials also described "terrorists" as hateful, treacherous, barbarous, mad, twisted, perverted, without faith, parasitical, inhuman, and, most commonly, evil. Americans, in contrast, were described as brave, loving, generous, strong, resourceful, heroic, and respectful of human rights.
Document 15: War on Terror: In a 'Letter to American People' written by Osama bin Laden in 2002, he stated that one of the reasons he was fighting America is because of its support of India on the Kashmir issue. While on a trip to Delhi in 2002, U.S. Secretary of Defense Donald Rumsfeld suggested that Al-Qaeda was active in Kashmir, though he did not have any hard evidence. An investigation in 2002 unearthed evidence that Al-Qaeda and its affiliates were prospering in Pakistan-administered Kashmir with tacit approval of Pakistan's National Intelligence agency Inter-Services Intelligence. A team of Special Air Service and Delta Force was sent into Indian-administered Kashmir in 2002 to hunt for Osama bin Laden after reports that he was being sheltered by the Kashmiri militant group Harkat-ul-Mujahideen. U.S. officials believed that Al-Qaeda was helping organize a campaign of terror in Kashmir in order to provoke conflict between India and Pakistan. Fazlur Rehman Khalil, the leader of the Harkat-ul-Mujahideen, signed al-Qaeda's 1998 declaration of holy war, which called on Muslims to attack all Americans and their allies. Indian sources claimed that In 2006, Al-Qaeda claimed they had established a wing in Kashmir; this worried the Indian government. India also claimed that Al-Qaeda has strong ties with the Kashmir militant groups Lashkar-e-Taiba and Jaish-e-Mohammed in Pakistan. While on a visit to Pakistan in January 2010, U.S. Defense secretary Robert Gates stated that Al-Qaeda was seeking to destabilize the region and planning to provoke a nuclear war between India and Pakistan.
