Pretty inplausable, but what if Brezhnev, during one of his bouts of dementia, orders the incorporation of Afghanistan as an SSR into the Soviet Union immediately after the occupation is complete in Feb. 1980.
1. It is materially feasible for the Soviet state?
2. Would ordinary Afghans accept it?
3. Would the US still be able to support seperatist Mujahideen fighters without starting ww3
4. How would the Mujahideen fair against domestic state security apparatuses? (KGB, et al.)
