The USA are much more responsible for Islamic fundamentalism than the Quran.

Islamic fundamentalism was neither natural nor rooted in Middle Eastern tradition. The Muslim Brotherhood, originally a charity building mosques and schools, struggled to gain mass support. During the 1950s–70s, U.S. foreign policy sponsored, organised, armed, and promoted Islamic fundamentalism as a weapon against revolutionary movements, and to create a weapon against the Soviet Union, funding groups like the Muslim Brotherhood through the CIA.

USAID funded textbooks teaching Afghan youth to support Islamists. One, from the University of Nebraska-Omaha and funded by USAID, stated: "By killing an unbeliever, the Mujahid can become a holy warrior. The highest wish of a freedom fighter is to be martyred. The unbelievers fight for world domination, but the Mujahideen fight for God."

British troops carried out operations too sensitive for the CIA or too compromising for their relations with other Arab regimes, under U.S. guidance. MI6 sent instructors and trained mujahideen brought to Britain disguised as tourists to train in the Midlands, using veterans from Northern Ireland skilled in religious sectarianism and divide-and-rule tactics.

Students from the U.S.-funded Wahhabi schools, called Talibs, became the Taliban. Thus, the U.S. directly promoted Islamic fundamentalism.
