Yeah but this kind of thing must be coordinated, even then operations on the Pakistan side must be carried ou by Pakistan and on the Iranian side by iran, we both need to work together
If this was unilateral, then you put Pakistan.in a tough position, even if you targeted terrorists
Because not responding makes Pakistan looks weak.
It signals to our enemies (not Iran) that Pakistan will tolerate violations of its sovereignty, which is unacceptable
Finally PAKISTAN MUST RESPOND failing to do so will encourage our enemies (again not Iran)
Their are enough problems in the region, and other enemies for Iran to suddenly act out this way inside Pakistan
The timing is TERRIBLE
