On the contrary, that's a handicap for us, vis a vis incubating any meaningful internal challengers to the TTA. America's occupation allowed them to freely arm, train, protect, and support anti-Taliban factions. The nation-building was to enable them to sustain the resistance after the US draw down. All of it failed. Pakistan has known this since before WOT and advised the Americans against it as well. We don't have a fraction of their means.
Our MO will be punitive strikes and economic pressure for every transgression while cultivating internal discord and then hooks within the TTA leadership.
PS: All our routes to Afghanistan are into TTA/Pushtun regions.
I was speaking with regards to the idea of Afghanistan's balkanization.
C'mon, buddy. Back it up.
