Nuclear deal is all about making the country self-sufficiency in electric generated power. It is a deal signed in between U.S and India in which India will be able to accelerate power for the country instead of buying it from the different countries.It is a process leading to growth and development of the country to become as one of the most developed countries of the world.
However, there is also the site of disadvantage as the country will never be the master of their own. Once again India will be under someone who will rule directly or can say indirectly. Because Induia will never be free to make their own missiles and weapons. If for instance there is an external attack on the country then India will have to wait for the U.S to seek permision to make weapons from Nuclear power.
