but they were the ones that repeatedly wanted to split NWFP away from Pakistan
Hope you by now know who wants NWFP to be split from pakistan. but paksitan's policy have always been like to oppose those people who have no claim on nwfp.
;and Pakistan needs a Pakistan-friendly government that does not cause trouble to it.
If you mean the taliban then only time will tell. i personally believe if taliban succed to come to power again which is unlikely to me, they will turn their political and proxy guns towards pakistan, they will probably ask for another Emarat in pakistan and also want NWFP to be split, dont forget that the taliban in Afghanistan is attracting its support from one group. do you think the taliban will forget isi's doulbe stance with them?
All I'll say about Afghanistan is: forget Pashtunistan and all those things, Pakistan is too strong for that,
I ask you again not tell afghanistan, tell it those people want your peice of land, not all groups in afghanistan want it.
