The problem with your statement is that you are thinking that JF17 will go into combat without force multipliers. Pakistan has showcased recently that despite having inferior planes, it can utilize other assets like DA20 and Awacs to create problems for an otherwise superior airforce. No plane will be fighting alone in case of war between India and Pakistan.
That makes it two of us. IAF would do the same. Question is - what happens after the first 48 hours !
