Al Qaeda, the Islamic State, and the Global Jihadist Movement What Everyone Needs to Know

Founded as the Soviets withdrew from Afghanistan, Al Qaeda achieved a degree of international notoriety with a series of spectacular attacks in the 1990s; however, it was the dramatic assaults on the World Trade Center and the Pentagon on 9/11 that truly launched Al Qaeda onto the global stage. The attacks endowed the organization with world-historical importance and provoked an overwhelming counterattack by the United States and other western countries. Within a year of 9/11, the core of Al Qaeda had been chased out of Afghanistan and into a variety of refuges across the Muslim world. Splinter groups and franchised offshoots were active in the 2000s in countries like Pakistan, Iraq, and Yemen, but by early 2011, after more than a decade of relentless counterterrorism efforts by the United States and other Western military and intelligence services, most felt that Al Qaeda's moment had passed.
