Not exactly:We moved out when US engineered comparable deals and turned the screws tighter.
Our majority of oil supply comes from middle east OPEC countries (AFAIK). Their Brent Crude prices are fairly above Iran's heavy oil prices.

I haven't seen any news of India getting cheaper than iran prices from OPEC.
It also matters how many boots, in what role and for how long. And indeed all Japan will do is smile when it comes to Pakistan / Afghanistan : they are simply not interested in this region.No boots no real leverage. WRT to Pakistan/Afghanistan all Japan can manage is a smile and a reasonably firm handshake.
Over a period of 5 years may be no, but over a period of 10 years may be yes. May not be 50 but surely 20 (18 in squadron with 2 in reserve). It is noteworthy that China does not have J-20 in numbers and J-20's engine is still not stealth or even fifth-gen. F-35 would have a definitive edge over anything Chinese could throw on us.We did not have the money to buy 114 Rafales. You think we could afford 50 F-35s?
PS - They are a bitch to maintain as well.
A plane that atleast can work is better than no plane at all. Even if it is bitch to maintain. Right now, we have no 5th gen plane and there is no plan of getting one. AMCA will come in next 100 years, if it at all comes.
Well lets see... US has enough trade deficit with us to arm twist us anytime. It does it quite often. Why do you think that we stopped buying oil from Iran?And US also arm twists countries when its industries need a boost. The order when conceived was 10 Billion USD. At a time when US jet makers were shutting down lines no way in hell US would let this chance go.
On that front btw, Russia does it too. Did Russia allow us to integrate Israeli missile in our Su-30MKI? And lets not even talk about the carrier.
