You are getting funny , now !
If its stupid tactic by Russian defence officials then they should have asked Pakistan in past at least 10 times ?
about getting , su-27 ,mig-27 ,mig-29, mig25, & su-30 ?
Please stop , your one eyed theories to make yourself happy , on the top of Pakistan is flying its home made , thunders on Russian engines ?lolzz
Accept the reality ?
Strong economy comes with , strong defence , countries without strong defence even having strong economies are reluctant on others to help them in any case of security matters , which make them slave to the ones with stronger defences ?
Japan & Germany are great examples , they can't do anything without the will of allied nations specially america & Britain ?
On the other hand , countries like China & Russia have built their economies on stronger defence , they are super powers enjoying , most of the powers same as USA UK ,FRANCE ?
So we need to build our defence further stronger , then of today ?
Even if we need to eat grass , same as the way we adopted , for our nucks ?
I can have a long debate about , J-31s getting matured & been inducted in PLAF & PAF , any how it will take at least 15 to 20 more years ?
What you think till then , no war will happen ?
& our crunt PAF inventory will be enough to counter any aggression against Pakistan ?
SU-35 & JH-7 combination can give us cover , range , fire power , tactical maneuvering , for at least 30 more years to come , in which we can make our economy able us to , invest or buy any 5th or 6th generation fighter aircrafts needed at that time ?
If we can secure our today , our towmarow will be better in all of our required terms ?
Or , we can try our best to become a economic power house like Germany & Japan , & asking permissions from UK : USA to conduct our army exercises ?
We have enough of the dam single engine fighters marvels like F-16s in our hands & we don't need them any more with their dam ABC's , & blk 52,53,54 ,55 600000 ?
We should stop wasting that money & instead ask our dam suppliers to bring some thing else ,
on our table like F -15s , if not then we can get it from any where we want ?
Any how still we have to pay those F-16S , SO WHY NOT WE PAY FOR MORE POWER & RANGE ?
