the US president has to submit a report each year on India's performance. The hyde act puts forward certain criteria which India has to follow inorder to qualify for a nuclear deal with US. If in one of the annual reviews, they find that India is not in line with hyde act, they can(have to?) withdraw from the act. By then India would be completely dependent on the nuclear fuel from Us and any lose of fuel would create major power crisis. No to mention all the multi million dollar nuclear reactors which will become useless. i am not saying this will happen but this could happen.
