The CIA doesn't give a damn for the military-money-congressional complex wars. The CIA cares about its own power, money, methods, and means - like the Mafia. They don't want a war with the people paying their (official) expenses so they keep their real scope of operations on the down-low.
Best believe they don't give a damn about what congress wants, what the president wants, or what the people want. They lied about Osama bin Laden doing his international man of mystery thing from a James Bond cave complex in Afghanistan because the Taliban cut off the supply of opium by more than 90%. The United Nations was helping the Taliban eradicate opium production. But once the USA and allies liberated Afghanistan from the rule of the Taliban that the USA had created to resist the Soviets, opium production mysteriously skyrocketed to levels higher than before the Taliban started its eradication program.
As noted previously, the obvious and predictable and actual consequences of an action being the real reason for the action, it was this resumption of the opium trade out of Afghanistan that was the real reason for the intelligence supplied by the CIA on the whereabouts of Osama bin Laden. The Pakistani intelligence service, ISI, is the CIA's Karachi branch office, the junior partner in this trade. The existence of a never-ending stream of military and CIA transports into and out of Afghanistan and Pakistan - whose contents can never be examined because "national security" - is the primary global smuggling method. The war profiteering, the extra-judicial powers afforded by the Patriot Act and the eternal War on Terror, is just a bonus.
As for the Afghan people, living in one of the poorest and least developed failed states in the world, lacking roads, airports, shipping, etc, and subject to military total information awareness surveillance on the ground, in the air, and from space, 24/7/365, these medieval peasants have somehow managed to smuggle millions of kilograms of one of the most illicit substances in the world every year for the past 819 years - "Afghanistan has been the world's leading illicit opium producer since 2001."
