We don't need to learn how to ride a motorbike, we only need to know how you are going to do it, so we can counter it.
And please, IAF pilots have been praised world over for their professionalism even in that infamous video by 'Youtube Terry'. We beat their asses in Cope '05 and we beat their asses in RF '08 (unlike what the video said) Your PAF pilots are nothing special outside of your collectively delusional brains.
Not at all. In fact they make me happy. MKI and MKK have completely different Radars, Power-plants, Control Surfaces, Electronics, EW suites etc. Russians rate them half as good as ours and even they don't know all about the Israeli, Indian and French systems on board. I want PAF to be as delusional and incompetent as you, so as to form their tactics on the basis of MKK.
PAF's poor F-16 C/D's OTOH, we know everything bout its jammers, radar freqencies, sortie generation rate etc. Even if we didn't, our fleet of MKI's is far superior to it anyway.
Singapore is a tiny city-state. They have very limited airspace so they have to rely on friendly states like India and Australia to train them. Not to mention if Singapore was attacked pre-emptively, they could lose their entire fleet in a single blow. Having their fighters around in rather strong countries who the aggressor is not gonna want to drag into war, ensures that some of their fleet would survive for payback.
