Does India need to conduct further thermonuclear tests to remove doubts raised by scientists?
If India wants to develop (and have confidence in) two-stage thermonuclear warheads, then it probably needs more tests, but if the goal is to have a credible nuclear deterrent then it doesn’t need more tests. The credibility is not about the type of warhead but whether India has shown that it can bring a nuclear device to explosion and that it has the delivery vehicles to deliver the warhead to its target.
