As I stated , the afghans are valuable residents (the none militants) and some valid card holder , so I don't believe on shoe fits all , to blame all people.
Folks who have adopted Pakistan as residence for over 20-30 years obviously do not want to go to a region where there are militants and Taliban - so it is also up to them to request a formal merge with Pakistan , and then a massive clean up operation can take place
A merge of afghan area with Pakistan is a a good future, but requires strong leadership in afghan territory to develop that on a diplomatic level
After that certainly militants will have to be tackled separately. I have only seen hard working afghan people in my personal experience , and it needs cooperation between both people
For the people caught on border , if they had no weapons and were innocent folks obviously they will have to return to their country
But afghan folks are hard working people and 100% Militants do not represent the values of Afghan province/region
And one always hope the folks caught in limbo would find way back safely
Obviously if Afghan province merged with Pakistan it would also benefit from CPEC indirectly but afghan region will have to demand that merge with Pakistan and on Diplomatic level
By means of merge the security would improve 1000%
Also a normal border would open as between any provinces
The issue in region really is militancy in "Un Administered" zones in afghan territories where not even Afghans go , the region does have bleak outlook unless a merge happens
Example:
Present Day USA , used to be divided between
(French , Spanish/Mexican , British (Irish/Italian/Immigrants from Europe), Native Indians)
But over time , all the states merged to form United States of America, the bigger goal of such merge was so that there is rule of law and no rouge "zone" exists for lawless entities like Taliban or Militants
Today most Americans identify themselves as simply Americans the past identities have been merged over 100-150 years or even 300 year period
What this example shows is the correct approach to tackle "Un Controlled Zones" or Areas which are under the law of Gun , or Militia , or Gangs lets call them as Gangs
USA offers people
- Citizenship (50+ states))
- Resident cards [Cards offered world wide known as green card]
The situation looks similar to Pakistan
- Citizenship card ( Punjab, Sindh, Balouch, Pashtoon, Kashmiri/North Areas)
- Resident card (Afghan migrants)
Only remaining thing is merging Afghan area into Pakistan and bringing law and order inside it by a joint effort
Free trade would also flow between old province and new province, and people obviously will setup business some may even move easily back moving economy (positively)
