It all has to do with financing before starting any operation; we need to cut off their financing for both BLA and TTP. Idk if its extortion, indian black money through Dubai, or drug money or oil smuggling
Whatever it is - you need to hit that on a priority basis and when the financing is gone, it'll slowly die its own death, hopefully. its all about $$$
Financing is one element, but we have to all consider that Baluchistan is a smuggling highway. The unchecked movement of goods from the coast, to the Iranian and Afghanistan borders as well as to other provinces means anything and everything is moving around constantly. While we don’t want to deprive law abiding citizens of the liberty to conduct business or personal matters, we need a better way to screen what transits the provinces.
Also, smuggling will only go down when normal economic activity picks up, which would require FDI, which requires political stability and a long term vision for economic development.
That is the carrot.
As for the stick;
the miscreants don’t think they will be found, locally or internationally. i would hope Pakistan, for the sake of a large share of Reko-Diq to the Saudis, gained access to the global Saudi lobbying effort to go after the backers of the BLA and TTP.
Furthermore, domestically, deterrence can be gained from building up a robust and wide spread QRF force. One the enemy knows will hunt them down till the job is done. This is where Pakistan should be trying to secure a large supply of new or used Cobras and Hueys from the US, with the good will build there, and perhaps some Saudi and/or Qatari lobbying if need be.
These helicopters are ideal for high, hot and humid areas, and large enough for long range operations. A large enough force that any attack on LEO in Baluchistan or KPK will be met with a quick ISR drone response within minutes and a heliborne force within 30-60 minutes will mean all miscreants attacks will be suicidal.
These aircraft have been battle tested in Afghanistan, especially in high tempo joint operations with ground forces.
Now couple this with police stations armed with fiber optic drones to better defend themselves until QRF arrives, and we have deterrence.
