The Pakistani military was already distancing itself from the various “good Taliban” factions which they had long-standing ties to, and that move seems to have been greatly accelerated in the backlash to this week’s massacre at a Peshawar school.
Not that it necessarily is justified. The Pakistani Taliban faction responsible for the strike was not one the military was on good terms with, and explicitly cited military offensives against them as a reason for their attack.
US and Afghan officials, who had long objected to Pakistan’s policy, mostly because the “good Taliban” were often openly in opposition to the US occupation, and not coincidentally regularly targeted by US drones, are expressing hope that the split is permanent, and will get the Pakistani military to attack these factions as part of their “retaliation” for the school.
It’s entirely possible, as the Pakistani government is looking for big death tolls to prove their seriousness about the massacre, and the usual Taliban targets aren’t as easy to come by.
