How about we do not give the air force the money and give it to our R n D people to make super sonic cruise missiles and submarine launched ballistic missiles or just buy them off someone I have no issues with either... just to state it plainly, whatever you give the PAF they will screw it up somehow or squander it...
They squandered the F 16s, they squandered sales of the Jf 17 and I think you can enlighten me with many more examples... We can do without a very strong air force because well, just dealing with the S400 will need a barrage of cruise missiles which are precise and very quick along with the whole shabang to take out that system... I do not agree with the premise that we need to continue throwing money into a flaming cauldron which just turns everything to crap.
Maybe order some J 31 and tell the air force to make do with the JF 17 till then... We can always get something from China if things go real bad...
