Bro,
For the sake of argument, let us assume that one PAF jet
somehow obtained a lock on one of these helicopters while it was attempting to flee to Afghanistan (this was post-Abbottabad engagement chase in reality), WE could not afford to exchange blows with Americans on ad-hoc basis, risking a much wider conflict, putting our entire country into choas and jeopardy afterwards. USAF was 100% active and watching our every move in the airspace and ground. Fazool mein nuqsaan karwalatey apna.
Americans destroyed a mixed force of Russian mercenaries and Syrian army in a firefight over control of a Syrian oil field, and Russian Air Force did not dare to intervene which it would have in case of lesser adversary.
They killed a terrorist - job well done. WE can make do with this.
Not just Pakistan, if India was in our shoes, it could not do anything either.
Absolutely, Sir. Well said.
