As I said, policy is dictated by leaders, so of course if Mr. Modi had some ax to grind against the States he could effectively do so. There seems to be a persistent issue with comprehension, I clearly stated that leaders meet only a few times with any important issue at hand, generally when they do meet on sidelines of summits then nothing much gets done, this has nothing to do with the fact that respective leaders play their part in policy formulation of running external affairs. How is it that everytime we cross paths you conflate two different issues erroneously. My statement is predicated more on the fact that Modi gives two hoots about such things than on anything else. His own words on the matter should take precedence even as per your own standards, no?
Watch from 30 mins onward, and then match that with my words, "As for Modi, I sincerely doubt that he cares too much about this, as for America, POTUS might find it a little awkward after all this to shake Modi's hand and sit down for a chat but it won't be anything that cannot be bridged"
Secondly, our system for ascertaining and enacting foreign policy is vastly different than that of the US- where historically their successive Presidents have taken the charge and actively run the state's foreign policy, in India it has always been an exercise of diplomats and a cohesive vision of the executive which involves the PM, FM, RM and MEA.
