Some other stuff I did, and across this theme I came:

What about uniting Pakistan and Afghanistan?

Would it stabilize the region, or rather de-stabilize further (is that possible)?
What would the neighbours say? Esp India and Iran?
What would that country look like and what role would/could it play in the larger region?
Would it be a threat? Would it turn extremist/lawless (more than now)? Would it be in permanent civil war (more than now)?
And what kind of structure could/should it have?

Without much analysis I say Durranistan could actually be a quite good idea! Based on a federal concept it could work.

Opinions?
