Wisest decision would be to scarp rafale deal and Tejas program all together and take offer of F16IN make in India , get 200 of these and all Indian fighter plane problems will be sorted out.
At the cost of 200 F16s , we can purchase 124 Rafaels, don't you think that would be a better idea.
Anyway, the idea of inducting TEJAS is not to give IAF cutting edge technology, which it already posses in the for of SU30, but to create an infrastructure which will enable us to create cutting edge technology in the near future.
If needed, we should scrap the 36 Rafael deal altogether, as this would further increase IAFs operation costs, maybe go for more super sukhois to fill in the numbers.
And to keep our French friends happy, award them a 10 billion $ submarine contract.
