This article likes to talk about Indian NFU policy and Indian nuclear 'restraint' vis-à-vis China. But then has sentences like this:
If India resorts to sending nuclear signals during a border fist-fight crisis with China, that reflects very poorly on any so-called Indian 'nuclear restraint'. It stinks of insecurity, having to wave the nuclear sabre when there is a border crisis with China going badly.
In any case, India is not in the same league as China wrt its nuclear arsenal. India does not have true thermonuclear weapons, no modern delivery systems, and a questionable ABM program. There is no contest.
The biggest nuclear problem for India is still Pakistan. If India attempts to increase its nuclear stockpile, Pakistan will follow suit. Both of their arsenals are comparable in size. But India would have to split its stockpile to assign them to both China and Pakistan. While Pakistan's stockpile is fully concentrated on India. With China sparing some warheads for India, the nuclear strategic balance is not looking good for India. In the longer term, this situation is likely to worsen as China is quite sure to rapidly expand its nuclear stockpile to counter the US-led anti-China alliance.
