This report examines India-Iran relations and U.S. interests. India's growing energy needs and its relatively benign view of Iran's intentions will likely cause policy differences between New Delhi and Washington. India seeks positive ties with Iran and is unlikely to downgrade its relationship with Tehran at the behest of external powers, but it is unlikely that the two will develop a broad and deep strategic alliance. India-Iran relations are also unlikely to derail the further development of close and productive U.S.-India relations on a number of fronts.
