There is nothing to say about the Su-30, its what it is, its what we need, you need to educate yourself about how the forces go about in incrementally enhancing their capabilities, yes once in a blue moon a platform comes along that is a game changer (typically a real force multiplier) but most of the time its incremental improvements.
You might be thinking, why is the IAF not retrofitting an AESA on to the MKIs, the IAF is concerned with more important things which effect its combat effectiveness, its more concerned with a networked ADGE, with proper C4I nodes and net-centricity, its concerned with its ground infrastructure, with the integration of a greater number and type of stand-off munitions etc. etc. (and that's a patent super simplification). On the other hand we jingos here tend to have myopic views, no knowledge of the macro level situation and we tend to get tunnel vision with regard to some specific fighter or that fancy new tank.
