A person engaged in jihad is called a "mujahid" (plural "mujahideen"). Operation Monsoon was the culmination of the government's efforts to quell the mujahideen insurgency. Abu Sayyaf proclaimed themselves to be mujahideen and freedom fighters. There were several sympathisers of the mujahideen within the military. In its roots, "mujahideen" (an Arabic word) refers to any person performing Jihad. He spent some time training with the "mujahideen" who were fighting the Soviets. These native militants remained, however, due to fear of ISIL's foreign mujahideen. Osama Bin Laden sent resources to the Bosnian mujahideen. However, the ICTY has never issued indictments against mujahideen fighters. Upon deserting to the mujahideen, soldiers immersed themselves into Afghan culture. They inspired him in taking an active role supporting the mujahideen in Afghanistan. Basayev wrote a book after the First Chechen War, "Book of a Mujahideen". After the Soviet withdrawal, the conflict between the mujahideen and the PDPA continued. The force was composed primarily of foreign "mujahideen" from Saudi Arabia and Yemen. Thus, Wilson directly influenced the level of United States government support for the Afghan Mujahideen.
