To determine exactly how good some spesific group of mens are is somewhat impossiple. Trying to solve it usually ends up very badly as nationalism and other irrelevant issues usually messes it up. Also without own expereince you cannot say anything solid about anything.
For example lets pretend someone askes who got the best artillerist. Well I would ofcourse jump out and say Finland as first i'm a finn and seccondly I have served with finnish artillery so I know what I'm talking about. But...(there's always a but) doesen't those two facts make me biased and thus unfit to awnser the question?? If we could close our eyes from the nationality-issue the fact that I've served only in finnish artillery makes me quite knowlidgble about finnish artillery, but I pretty much know about (mostly about the little matters that usually makes the difference) other artilleryes as much as any other that haven't served...So the expereince wont help you in the end to determine whos the best (wheter it's artillerists or pilots)
Seccond important factor is the actual results. Some countries have combat experience and we can try to analyze the results to find out who's the best...but then we face yet another proplem...the skill of the performer isen't the sole factor that leds us to the results. No matter how good you are, there is still factors that you cannot inflict. such as the equipment you are using, the
maintenance and support (I highlighted that becouse so many armchair generals tend to forgot it...), enviroment, wheater...you name it, there are lots of variables. So even well documented facts cannot indisputably say they are better than the others...
So to determine who has the best pilots in the world (or how some countrys pilots are rated) is like determing the best rock n' roll band in the world...I say it's Led Zeppelin, many facts supports me, but...is it???(ofcourse it is, but to play along with my thetis I must act like there could be some doupt
)
So who capaple are pakistanese pilots?? They are as good as you want them to be...
