As one goes through the text of the India specific draft agreement, which the country will submit to IAEA, there is absolutely nothing that would stand in the way, either by way of restriction or limiting the country’s sovereignty in clinching the deal.
Now, India will have unlimited freedom to acquire nuclear fuel from the NSG for the existing reactors and new ones that are to come up in the country. There is a clear demarcation placed by India, to keep about half-a-dozen indigenously built reactors from the purview of IAEA. They would be fuelled by indigenous technology; most of them are fast breeder reactors, producing plutonium for our legitimate defence production.
The heartening part of the agreement is that India is recognised as nuclear state, with a freedom to explode a device whenever necessary. The agreement gives the country the freedom to approach any country, in the list of (NSG) Nuclear Suppliers Group; this paves the way for more flexibility and freedom in acquiring nuclear fuel.
Therefore, there is no reason for the Left or BJP to sulk, with regard to the Indo-US civilian nuclear deal.
