Pakistani internal security (catch all)

[jmm99]

1. Are the Pashtuns a monolith (as in the very basic map attached), or are they divided into distinct sub-groups geographically ?

2. If sub-groups, which (if any) are cross-border living in both Pstan and Astan ?

3. If sub-groups, which are Taliban-influenced ?

4. Is the Taliban a monolith, or does it have its own factions ("hard" to "soft" or some such qualitative measure).

The overall question is whether there are Pashtun sub-groups which the US could work with directly.
