Would you trust a European radar that is still in development? Why bet on an unknown horse? Could you trust the European countries not to impose sanctions in the event of a war with China / Pakistan? Remember Europe is also trying to sell to China. We would never do that for strategic reasons.
The Rafale has always lost out to competing vendors. It might make the short list of the countries that you mentioned but what are its chances of winning those bids? If you go for the Rafale it is highly likely that you and France will be the only TWO countries flying it. Yes, that gives you leverage BEFORE you make the deal. But the servicing / lifetime costs of that plane will be a lot higher.
I understand why you are happy with Dassault. In comparison to your Russian vendors, dassault might look like a great company. But LM and Boeing have an unmatched track record in service
How proven are the American radars vis-a-vis the Euro ones???Again open to debate,coz all sensible nations will export only downgraded systems when it comes to the point be it the European AMSAR or Raytheon APG-79.The chances of Europe imposing sanctions are the same,if not a little lesser than that of the US-history has proven that part.If Europe will sell to China,well, India's largest supplier,Russia already does that.And the US arms Pakistan.It's a big bad world.
If the Rafale hasn't had any buyers,well so hasn't the F/A-18 E/F which has evoked little interest outside the USN & the SuperHornet is the only one with a chance to win the IAF contract.The level of support offered by LM or Dassault is directly proportional to the state India's ties with those mother nations.Enuff said!!
