I do not believe that the war was "not winnable" in Afghanistan. The Soviets managed to defeat the Taliban precursors (Mujahideen), and left behind a Soviet-propped government that lasted longer than the Soviet Union did (3 years after they left). That's as close as you can get to an example of a "win" in Afghanistan -- so don't say that the war was not winnable.
