The two occassions we tested, we attracted sanctions. In fact the NSG was created as a reaction to PokhranII conducted by the NDA govt. So even before the deal we test, we attract the same sanctions. However, after signing the test, if other countries test, it permits India the right to test.
There was a huge time gap of nearly 3 decades between India's first test and the second. Did it any way curb our progress in developing our military program? No way.
We do not need to physically test any more. All over the world this is done by computer simulation using past test data. This is why Vajpayee govt conducted a series of 5 tests to generate the database and then he and Jaswant Singh went on the floor of the UN assured the world that we are not going to test further.
So when was the last nuclear test conducted by any country in the world - not since a decade. The exception being N Korea. And it will remain that way as all nuclear powers have informally agreed that they will ban physical tests
