When the Soviet Union intervened in Afghan Civil War, they created a spiral of violence that is still going on till this day. On the one side the Soviet troops weren't able to gain control over the huge country. On the other side, the US, via the CIA, and the Arab countries supported guerrilla fighters with arms deliveries. These militias called themselves Mujahideen and thought that they are fighting a Holy War against the infidel communists. Even after the retreat of the Red Army, Afghanistan remained in chaos, the Taliban seized power and after 9/11 NATO forces invaded the country and made the same mistakes the Russians did before.
