This article is wrong. India should not test its H-bomb again, even if the original has been an abject failure. Nothing good can ever come of it. Sanctions from the west (after a hard won nuclear deal) would be disastrous to the 1billion poor of India's 1.2 billion people.
Since Pakistan does not have any N-bomb, India's only arguments for building the bomb are threats from China. But how will building one h-bomb ever act as a deterrent? China has tons of them. And if India builds one, china can build 10. They have the know-how.
India should work on its h-bomb only if it is known for sure that Pakistan is proceeding with its h-bomb plan (which it is not, right now).
And by this time, India should have realized that the largest threat to its stability is (a) Inside Maoist Rebels (b) Islamic terror which is destroying Pakistan right now. China does not figure in that list. Only some perverse ultra-nationalistic alarmist would think of China as a threat rather than an inspiration.
Throwing the sub-continent into an arms race and unifying the Pakistani people in hating India is certainly not what India needs right now. India and Pakistan must join hands and destroy terror in Pakistan - India's own self interest lies in this.
No amount of thermonuclear devices, no amount of N-bombs will ever quell the threat of terror. Talking about these devices is an immoral waste of time.
