So I've been wondering on this issue lately: how much territory can the state of Pakistan reasonably expand to control? I've heard all sorts of suggestions both on this forum and elsewhere from the more standard (i.e. Pakistani Kashmir and possibly neighboring Jammu) to the rather unusual (union between Pakistan and Afghanistan).
I don't attach qualifiers, bonuses, or any sorts of "challenges" to the question of precisely how much Pakistan can hold, and perhaps more importantly, what would actually benefit Pakistan?
