I think my effort to explain the devastating economic crisis due to these mega billion dollar imports on fragile economy didn't paid off. You are saying that aquisitions in last decade don't make sense according to official budget. Well it all makes sense perfectly seeing how the economy is nose dived. You are suggesting, that the defence budget is even more then what's displayed but still if you are unable to pay upfront then its even worse as you will pay with heavy interest over the years and decades.
Now when PAF has selected J-31, I don't see any supply chain, any logistic, any financial or any wildest possibility of KAAN in PAF inventory in next 10 years. For next 10-15 years KAAN is going to use American engine anyways. Which is impossible to get for PAF in the first place. KAAN may enter into PAF service much later than what you are anticipating.
