They can be extremely expensive, but it is possible that we may require this power eventually. Suspicions on Americans run deep, surely they cannot be trusted, but how long we could watch the issue. 20 years down the lane, we may not have people as good as we have them today in the nuclear field, and will be at the mercy of Americans. It is time to think, we have let ourselves down over the years, corrupt politicians and bureaucrats the development has become one sided with rich becoming only richer and no second way. We repeatedly fell to the lures of money and got ourselves exploited by people like Ambanis. So it won't be too far before Americans employ the same tactics. Same tactics and same result over and over again, probably till the end of one and all.
