But I heard they are getting rid of that thug (Mehsud) through the local warriors i.e. Haqqani and Nazir without the army intervention.
Haqqani & Nazir groups are ISI funded from the start, they were built up to counter the threat of Mehsud like people coz Army doesn't have any approach in those areas.
If you look at the Map of FATA/NWFP, Army is moving according to a long-term strategy in which they will have permanent cantonments in that region.
We have to understand we just can't leave the security of western borders to some pyscho tribal's, that's our land we have to take care of it same way we did with eastern.
In coming months & years, you will see Army building bases in FATA/NWFP.
