Passage :
Efforts are on to generate favourable public opinion for allowing our government to sign the Comprehensive Test Ban Treaty (CTBT). It appears the government has been trying to sell to opposition parties and the public the following point:
Our nuclear scientists are sure that with the Pokhran –II tests, conducted in May 1998, they have “enough data, expertise and skills to conduct sub-critical test and maintain our deterrence for the next 25 years or so,” and therefore, we can go ahead sign the CTBT. India does not need any further nuclear test for weaponisation and for acquiring a minimum deterrent. If we sign the CTBT now, there will be every possibility of the American Government supporting India to get a permanent seat in the United Nations Security Council.
