Yes, Anurag, we have to deal with Pakistan as well. But Pakistan will religiously protect the pipeline as it would be to their benefit to do so. Iran will also do likewise. After all, they are also going to invest their man and machine there.
The Pipeline business will remain purely economic and its up keep will be benefiting perennially to both those countries. Rather India is Blackmailing in a way to both of them. After all if India do not consume the Gas, it will go waste as there will be no one to consume it. And Pakis are getting money for doing nothing.
