Charlie Wilson's War (2007)

In the 1980s, Congressman Charlie Wilson is more interested in partying than his legislative duties. When he learns about the Soviet war in Afghanistan, he decides to help the Afghan Mujahideen. With the help of a romantic interest and a maverick CIA operative, Charlie doubles the CIA budget to support the rebels. Through political bargaining and careful planning, they supply the guerrillas with weapons and turn the Soviet occupation into a deadly quagmire. This covert operation becomes a major part of U.S. foreign policy, known as the Reagan Doctrine.
