Just Close and the seal the fricking border so they stay there!!
Building walls wont work:
That's wishful thinking. Sealing border isn't very easy unless you are Israel with almost unlimited resources and a relatively small area to build wall around. Laying mines is also not very practical due to length/ type of terrain. Take Mexico for example, although US does a good job stopping illegals with their fancy gadgets, there still are some shortcomings in total protection/ sealing of borders. And Ts are experts in tunnels/ caves because they and rats have many common traits including brain size.
No surprise:
This was expected of Afghan not because they want to return some favor but they are just not capable of dealing with their own Ts in "under control areas" forget additional Ts fleeing from Pakistan. With NATO in a hurry to leave Afghan there is more pressure on Afghan forces to "maintain" (Although they hardly have any) control over their areas.
One idea:
Method should be breaking the infrastructure within Pakistan, elimination of the concept of "holy warriors" and "Jihad because we are bored", and a way of uniting tribes against Ts to safeguard their areas and not be bullied by return of T-virus if Army concludes operation and returns but at least leaving behind and planning for bases in the area for rapid response. Because weather you like it or not, some Ts are going to come back to Pakistan weather we push them into India, Afghan, Mars or Jupiter, how much and how armed can be controllable variables.
Future Improvements:
Along with rapid response forces, Pakistan should invest in drone/ surveillance technology. But maximum control of areas will come when there is serious development in those areas. More civilians there happy with govt, more willing to co-operate with govt. Similarly with Baluchistan, give them reasons to drop their BLA BS. These parts of Pakistan hide very many resources within. Explore an use them for Industry, jobs etc.
I have lived my life with this phrase and it has served me well. Same idea applies in this scenario, "
If you wana get something done right, you gotta do it yourself."
