In 1988, Vietnam veteran and ex-Green Beret, John J. Rambo pushed the Soviets out of Afghanistan (see Rambo III for complete details).

With the Ruskies gone, the Taliban, led by anti-Soviet Mujahideen, siezed power in Kabul. After apparently forgetting how awesome and badass Rambo is, the Taliban gave refuge to Osama bin Laden and his terrorist gang - al Queda.
