Hamish, the Indians have a mixed country of purchase inventory in aircraft, so therefore are not beholden to one single state. They fly British (Sea Harriers) French (Mirage 2000) and Soviet (SU 30 Flanker H) designed combat aircraft.
Whilst it may take time for the Iranian air force to learn the new systems, only they know their time scale to full operational capability and more importantly what they want to do with it.
The Indian gave the Americans quite a shock at Cope India, who is to say others cannot do the same given enough time, money and ability.
Are people going to be advocating the same road as recent history and a dodgy dossier perhaps.
The French as usual will do what is best for France and NOBODY else.
