Synopsis for
Charlie Wilson's War (2007) More at IMDbPro »

"Good-Time Charlie" Wilson, a flawed and fun-loving Congressman from the piney woods of East Texas, deftly operates the levers of power to funnel money and weapons to the Mujahedin of Afghanistan following the Soviet invasion of their country in late 1979. Charlie finds assistance in the oddest of places -- a renegade CIA agent whose outsider status and womanizing ways endears him to Wilson; a Houston socialite who leads Wilson to the cause; the willing Pakistani dictator fascinated by the socialite; the Israelis who modify and manufacture Soviet weapons to maintain the wink-and-nudge illusion of American neutrality; and the women -- ooh the women.

Based on the story (and the excellent book of the same name) that is so true and engaging that artistic liberties are not needed, even if they are taken in the film.
