Following the events of September 11, 2001, the name of the al-Qaeda organization, as the terrorist group leading to attacks, quickly spread all around the world, and this group and its leaders and activists were prosecuted. The organization, rooted in Salafi and fundamentalist extremist thoughts, has always been supported by the West and the United States during the Cold War because of his struggle against the Red Army in Afghanistan. But the end of the Cold War and the spread of al-Qaeda’s thoughts to other Islamic countries, as well as the meaning crisis of the end of the Cold War, gradually led to the introduction of this group and similar organizations as enemies and fighting against radicalization of Western policy in the region.
