It was always known that Hyde act was going to be an issue. It is unlikely that congress will issue a waiver for India. It is also not clear that congress can issue waiver for an individual country.
Given the growing relationship with Israel, Indian lobbyists in US congress should seek help from American Israel Public Affairs Committee. Israel and India both are victims of terrorism by Muslims, both countries have great democratic tradition, both are beacon of tolerance; hostile neighbors who are out to destroy them surround both.
India has to convince USA that India is as valuable a friend as Israel. Only then she will be able to get a waiver that she richly deserves.
