I dont see why India needs another nuclear test, because if there is contradiction now in the deal then there was contradiction given by the Indian government and indian Nuclear scientists after the test, because then India had declared the all their Nuclear tests were succesful and it would not require any more tests. On the other hand also India does not need any more sanctions and isolation when the Indian economy is booming although Inflation is still the big Monster but I am sure that it will be taken care of. In current scenario all India needs to do is get itself involved with most of the major coutries be it on space project or defence projects. China is moving ahead in the african countries and making a firm grip in those countries they are investing huge amount of money in several countries and starting new projects over there and staking huge amount of money in their Natural resources, like currently they went into a deal with Congo worth somewhere around 9 bn Dollars, where in they will be constructing roads and exploring the coal mines where in they will have more then 50% of stakes, what china is doing is securing energy and natural resources for its future growth on other hand India is lacking far behind. India needs to secure its current future Energy requirements. Reason behind India and China border dispute is the natural resources in Arunachal Pradesh, Chinese know it so they are eyeing it and at same time they also dont want India to explore AP freely.
