Perhaps I overstated the case against him, but I just believe that someone who dogmatically adheres to the theory that Russia did not lose the Russian-Afghan war (because they were able to install a puppet government that managed to hold out for a few more years before being destroyed by the mujahadeen), is kind of off his rocker.
But that's just me!
I hold that theory too. The USSR did not lose the Afghan war. Their man (Was it Najibullah?) stayed on in poewer in Kabul well after the Russians left. The Mujahadeen never took Kabul and never knocked out Russia's allies from the war.
