The United States and India began work this week on redrafting an agreement that would scrap a three-decade ban on Washington trading nuclear technology and fuel with India. The fate of the deal rests with the forty-five countries in the Nuclear Suppliers Group. The group will meet again early in September after talks broke down last week. The United States is expected to rework the waiver to the embargo, which has been in place since India tested nuclear weapons in 1974.
