Separation of India's military and civilian nuclear programmes:
This is not only India's perogative but India is the only authority on it. US can only wish that all civilian facilities are placed under safeguards, it cannot make that happen. Recently it was in the papers that the Fast breeder reactor progamme (has not been/will not be) placed under safeguards and hence will not recieve technological inputs from other nations.

The fact that in India nuclear research has never been classified as civilian research or military research is a problem. Segregation of facilities will definately prove to be expensive (moneywise), as India won't be able to use spent fuel or byproducts of civilian programme in the strategic programme.

India must always be wary of US for the simple reason that US is not a peaceful nation; Americans just love wars. For the last 100 years it has always been at war. There hasnt been a 20 yr period of peace for the US armed forces. Its also interesting to note that Israel, created by Americans; Pakistan, supported by Americans; Taliban, nurtured by Americans;(there must be a few more) have also been a source of conflicts.
