It is very simple. You can operationalize the deal and get it sold to UN body. After it is all said and done, don't buy any thing related to Nuclear field from US. There are other like France/ Germany who will be more than happy to supply India any thing it needs. If you don't bu any thing from US, how can US blackmail you.
Besides, in US not even US utilities are currently buying US reactors. Most of them are going for AREVA (French/German). Westinghouse and GE Nuclear power Plants will be built by Toshiba or Hitachi in future.
Niketas in India want to drive the economy to grave that where the constituency is, in slums.
