why Would the Russians supply the Taliban with weapons

There was a report on Conservative Radio today that the Russans would sell Surface to Air Missels to the Taliban. Why would they supply the Taliban when so many brave soldiers of Russia died there fighting the Taliban.There was a report of a Russian Arms dealer caought trying to sell arms to terrorists. Russia need to crack down on such people in their country.li We need to improve our relationship with Russia and convince them to help us defeat the Taliban.  The US did supply the Taliban with weapons and Surface to Air missels when Russia was there.  If we did not do this the Taliban would not be problem today and we would not have suffered the events on 9/11/2001. So many of our countries problems are from a messed up forigh policy.  I pray the troops in Afganistan and Iraq will return home soon and that they are safe. We cannot police the world alone.
