U.S. military killed bin Laden in Pakistan in May 2011. Al-Qaeda members believe a Judeo-Christian alliance (led by the United States) is conspiring to be at war against Islam and destroy Islam. As Salafist jihadists, members of Al-Qaeda believe that killing non-combatants is religiously sanctioned. Al-Qaeda also opposes what it regards as man-made laws, and wants to replace them exclusively with a strict form of sharīʿa (Islamic religious law, which is perceived as divine law). It characteristically organizes attacks such as suicide attacks and simultaneous bombing of several targets. Al-Qaeda's Iraq branch, which later morphed into the Islamic State of Iraq and Levant, was responsible for numerous sectarian attacks against Shias during its Iraqi insurgency. Al-Qaeda ideologues envision the violent removal of all foreign and secular influences in Muslim countries, which it denounces as corrupt deviations. Following the death of bin Laden in 2011, Al-Qaeda vowed to avenge his killing. The group was then led by Egyptian Ayman al-Zawahiri until his death in 2022. , it has reportedly suffered from a deterioration of central command over its regional operations. Organization Al-Qaeda only indirectly controls its day-to-day operations. Its philosophy calls for the centralization of decision making, while allowing for the decentralization of execution. The top leaders of Al-Qaeda have defined the organization's ideology and guiding strategy, and they have also articulated simple and easy-to-receive messages. At the same time, mid-level organizations were given autonomy, but they had to consult with top management before large-scale attacks and assassinations. Top management included the shura council as well as committees on military operations, finance, and information sharing. Through the information committees of Al-Qaeda, he placed special emphasis on communicating with his groups. However, after the War on Terror, Al-Qaeda's leadership has become isolated. As a result, the leadership has become decentralized, and the organization has become regionalized into several Al-Qaeda groups. Many terrorism experts do not believe that the global jihadist movement is driven at every level by Al-Qaeda's leadership. However, bin Laden held considerable ideological sway over some Muslim extremists before his death. Experts argue that Al-Qaeda has fragmented into a number of disparate regional movements, and that these groups bear little connection with one another. This view mirrors the account given by Osama bin Laden in his October 2001 interview with Tayseer Allouni: however, Bruce Hoffman saw Al-Qaeda as a cohesive network that was strongly led from the Pakistani tribal areas.
