So, by Europe you're pointing at EuroFighter Typhoon.
Country in the North is Russia.
And finally, you said USA.
Europe (EuroFighter Typhoon): Which Tranche are you targeting? Can you (Pakistan) even afford the cost of its maintenance when European nations are giving up on them & putting them in storage. Its no surprise they are trying to shove them down the throats of countries like Indonesia (who passed on the offer) & now Bangladesh. There is a term for people like that. SUCKERS!
Russia: Have you found the hack of how you're gonna bypass CAATSA? If so, we're all ears.
USA (F-16): The fact that you're getting J-10's today is a clear indication that F-16's were never on the table. They could have been - depending on us bending over and being the US's b!tch for another a few decades.
That being said, I won't let it by me that Pakistan didn't try on a number of occasions - whenever they had a chance. But in the end, when it comes to the US - its all about "What are you willing to do for us?", followed by "Here's a list."
