A joint development makes only sense when both partners are equally capable … here India can contribute almost NOTHING but money, so from the standpoint of shared technology, India would benefit, while France would / should transfer … and that won‘t happen!
In fact NO country would sell or transfer its crown-jewels of technology for a few $$ and in fact $7 bin are peanuts in comparison to decades of research, investment and experience. Like I said so often already. India must do it alone, it‘s like walking. Calling each time for mom and dan or an uncle or aunt is still not walking alone.
And in mind of a few more Rafales, just forget it,it no argument for a ToT. Either you accept this and do your homework or you won‘t even more get neither an engine nor additional Rafales.
The terms of this deal will be solely made by France, period … discussing this again and again is like discussing what would change if the sun rises in the West! It won‘t ever happen.
