query: What is the purpose of terrorism?
passage: Terrorism
Terrorism is, in the broadest sense, the use of intentionally indiscriminate violence as a means to create terror among masses of people; or fear to achieve a religious or political aim.[1] It is used in this regard primarily to refer to violence during peacetime or in war against non-combatants.[2] The terms "terrorist" and "terrorism" originated during the French Revolution of the late 18th century[3] but gained mainstream popularity during the U.S. presidency of Ronald Reagan (1981–89) after the 1983 Beirut barracks bombings[4] and again after the 2001 September 11 attacks[5][4][6] and the 2002 Bali bombings.[4]
passage: Islamic terrorism
Al-Qaeda's stated aim is the use of jihad to defend and protect Islam against Zionism, Christianity, Hinduism, the secular West, and Muslim governments such as Saudi Arabia, which it sees as insufficiently Islamic and too closely tied to the United States. Formed by Osama bin Laden and Muhammad Atef in the aftermath of the Soviet–Afghan War in the late 1980s, al-Qaeda called for the use of violence against civilians and military of the United States and any countries that are allied with it.
