9/11 should have been the ending
This film should have ended with the planes crashing onto the WTC. 9/11 is alluded to in the film for good reason. The mujahideen, and Osama bin Laden among them, known as "freedom fighters" in the US, first received American arms and were trained to fight a jihad against the Soviets, then fought each other, until the Pakistan-backed taliban controlled the country.

Actually American aid to the mujahideen started about 6 months before Soviet intervention according to Zbigniew Brzezinski, national security advisor to President Carter: "According to the official version of history, CIA aid to the Mujahadeen began during 1980, that is to say, after the Soviet army invaded Afghanistan, 24 Dec 1979. But the reality, secretly guarded until now, is completely otherwise. Indeed, it was July 3, 1979 that President Carter signed the first directive for secret aid to the opponents of the pro-Soviet regime in Kabul. And that very day, I wrote a note to the president in which I explained to him that in my opinion this aid was going to induce a Soviet military intervention."
