Sorry a misstatement on my part. I meant Al Qaeda which originated during that time. Osama was present during the Russian occupation. I got my terrorists mixed up.
I believe that Al-Qaeda itself didn't exist yet during the Soviet occupation. I believe that it was called something else...Makbat al something, I believe. It was dubbed AL-Qaeda after the Sovs. left.
BTW, the Taliban did indeed include former Muj in it's ranks, however, the same Muj organizations that we backed during the Soviet war were the ones who fought them and later became the Northern Alliance.
