But entire pakistan is in range of US, don't forget it.US cannot hunt down hidden Taliban, but it will not be the case for Pakistani Army.
And as yr ISI is playing double games with US, i am afraid above scenario can be happen in near future.
But r u concerned about what will happen if US will leave Afgan now?
Talibans will take over it.
I accept that US should leave Afgan,but in the present circumstances where Afgan is not stable it will harm Afgan.
