Listen kid, the attack from 2013 that 14 of our border guards got martyred was because of a ambush, a sneak attack, a cowardly backstabbing attack that happened in the middle of the night. Right after their heinous crime they fled back to the other side of the border.
Fleeing to Afghanistan is no option for them as it is a long way to drive on the borders and chances increase for the Iranian helicopter gunships taking their asses out or get overwhelmed by Iranian forces.
Easiest thing for them to do is just flee like rats into Pakistani territory. Considering Pakistan multiple war fronts the area around the Iran border is void, so its a safe paradise for them.
Now what we want is
1.Pakistan issues the permission for Iranian special units to come,locate and get the hostages back, by pure force.
2.Pakistan ignores,denies, Iran goes in themself, and any eventual clashes between Pakistan and Iranian armed forces will be solely blamed on the Pakistani authorities for TOTAL negligence.
Either issue the permission or stop crying when we come in ourself.
