I believe that our main issue with India at this time is its pursuit of nuclear weapons. If the US had a deal in place with India regarding nuclear weapons, a trust would be forged that would allow the US to trust India more in all aspect of foreign relations.
A deal will not improve strategic relations between the countries it will simply be a paper promise between countries who will continue to do what they feel is best while pretending to get along. The difference in priorities in each country and their different level of advancement in the field will always be a source of contention. On paper there will be strategy but in practice there will be side-eying and mistrust.
