But SU was not able to solve the problem because Pak was constantly thwarting their attempt by arming the mujahideens. A natural reaction would be to neutralize threat at its source. Pak was not nuclear at that time.
Reviving an old thread.
I still cannot understand why SU did not invade Pak, when it knew that they were harbouring all the Mujahideens. @gadeshi , @Cadian - any perspective?
