On this occassion the left is right. Two or more reasons:
Once the document becomes operational it is not the Supreme Court of India that will interpret its provisions; rather, it will be a foreign agency dominated by USA or China or whoever else that will have the dominant role in interpreting the provisions. Mind you, it is the interpretation and not the print that counts. And our government will be pressurised unnecessarily to the detriment of the country. We ought not let anyone set foot on Indian soil in the garb of inernational nuclear inspectors or similar because the places and the things they will intrude into will be decided by outside powers and the country will not be able to do anything to stop them. We should learn from the experience of other countries.
Secondly, India will be obliged to keep and open its nuclear accounts for inspection by the outside inspectors or powers. It will unnecessarily limit the deterance value of its nuclear posture.
Instead of entering into this arrangement what India should do is to develop its own reservoir of nuclear material on a slow but steady pace without outside interferance.
