It will be a govt to govt deal with the Americans. We dont buy and the Americans cant supply that much oil though that's one component in reducing the deficit. I'm just pointing out that this offers us a way out on the deficit situation (provided we have the money to buy anything...) and going with Rafale again would be stupid when there are zero gains with that decision.
Also with oil, we can only buy some quantity from the US without cutting down too much on our traditional suppliers. Nobody will take kindly to India reducing drastically oil supplies from the Arab countries. It's why, more than ever, military deals offer the best solution to this problem, though even there, we do a delicate balancing act.
As I have said earlier, India's foreign and military dealings are like the weekly hafta payments to the goobs around..the Americans, Russians and the French. We have to and we pay..everyone.
