Is NPT a club of nuclear haves or nuclear Have-Nots?
India argues that the NPT creates a club of “nuclear haves” and a larger group of “nuclear have-nots” by restricting the legal possession of nuclear weapons to those states that tested them before 1967, but the treaty never explains on what ethical grounds such a distinction is valid.
