This is definitely the time to act, this winter, while they are busy dealing with the humanitarian crisis;
1. finish the fence (Afghanistan and Iran) once and for all, and build a no mans land a kilometer wide to prevent enemy snipers getting too close.
2. Build massive forts along the border on the high grounds (preferable in a star fort design so troops can’t be out flanked)
3. Put up enough remote gun systems at these forts so that solders don’t have to be exposed to enemy fire unnecessarily.
4. Equip forts with ISR and affordable precision attack systems, so fights are quick and decisive, and troops don’t have to peruse miscreants across the border.
5. find and eliminate miscreants in Afghanistan, wherever they are. If possible to some snatch and grabs, of the TTP leaders that are officially Pakistani citizens, to have them stand trial for the satisfaction of the APS families.
