Seems very plausible. This will hit two targets in one shot.1. They will get Americans out of Afghanistan and install a puppet regime there and 2. With the help of Haqqani group they will handle the native Pashtun population of waziristan.Pakistan Army is planning to hand over the control of Waziristan to Taliban. According to Afghan peace deal, Haqqani boys need to go back to Pakistan in 6 months & Pakistan Army is planning to bring Haqqani boys to Waziristan. Peoples in FATA know this and they are rallying behind PTM to stop that.
Earlier they tried the same thing with afghan taliban but got TTP in return. But looks like they are willing to take the risk again to settle the “Pashtun problem” permanently
