Let's say a different US leadership decides to partition Afghanistan after 2001. My idea is that the war is worse than IOTL and by 2010 the US decides that partitioning is the best course of action.
A partition of Afghanistan means that it is pretty much a given that the northern areas of Afghanistan which is comprised of Turkmens, Tajiks and Uzbeks becomes independent. Its name might be Khorasan.
I think that maybe an independent Balochistan might be carved out of southern Afghanistan yet I don't think Pakistan will be fond of the idea. The early 2010s were not a good time for US-Pakistan relations what with the skirmishes, Operation Neptune Spear and Raymond Davis so a more hawkish leadership might create an independent Balochistan in Afghanistan as a warning to Pakistan.
Hazarajat has the chance of becoming an Iranian client state, so there is a good chance that it might not be independent. Maybe it becomes a part of Khorasan, or it remains a part of Afghanistan. Then again, an independent Hazarajat could mean that Shias in Afghanistan are safer.
What do you guys think? How will it impact Afghanistan and the war there?
