I cannot believe this thread but I have come to expect no better from our western neighbours. Both F-16s and Su-30MKI are very capable fighters and when it comes to real engagement a lot depends on the circumstances, numbers, pilot skills, AWACs support, etc. Even if we conclude that F-16s are as good as Su-30MKIs (which is entirely untrue), IAF has MKIs in far greater numbers - at least a 3:1 ratio which is more than enough to dominate any large scale engagement on the western front. On the East, it is highly unlikely that China will make the mistake of messing with India because 1) US is looking for any opening to come in and tame the dragon. 2) Both US and India are very important markets for China and unlike our western neighbours they are much more sensitive to the virtues of economic growth than indulging in costly wars over small disputes.
