India's puny atomic weapons are a joke. If India chooses unrestricted nuclear warfare, China will end Indian civilization.
There are Indian atomic weapons and then there is Chinese multi-megaton thermonuclear weapons. These are very different nuclear powers.
India only has low-yield atomic weapons. China can do what it likes.
China must never allow expansionist and imperialist India to develop thermonuclear weapons. It was only decades after independence that India annexed Sikkim (in 1975) and South Tibet (in 1986). The British have gone home and left their former Hong Kong colony. The Portuguese have also gone home and left their former colony in Macau.
We will eventually kick Indian imperialists out of Sikkim and South Tibet and send you packing.
Currently, India only possesses pathetically weak 4 to 25 kiloton atomic weapons. In comparison to a single Chinese 3.3 megaton thermonuclear weapon (which is over 100 times more powerful), Indian atomic weapons are like little firecrackers. However, at an unknown point in the future, I believe India will eventually develop a crude thermonuclear device. It could be 25, 50, or 75 years in the future.
Regardless of the exact time of India's development of a crude thermonuclear bomb, I have already formulated China's strategic neutron-bomb response, military control of Indian airfields, and survey and collection of the raw ores (e.g. uranium, thorium, and existing plutonium) to produce Indian fissile material.
A future Indian Nehru must never possess the capability to truly threaten China.
U.S. Lawrence Livermore National Laboratory concluded the Indian thermonuclear device was a failure.

Rankings of world P-5 (i.e. Five permanent members of the U.N. Security Council) thermonuclear powers by megatons of firepower:
1. Russia - 1,273 megatons
2. United States - 570 megatons
3. China - 294 megatons (China has over half the nuclear firepower of the United States)
4. France - 55 megatons
5. Britain - 16 megatons
Humorous fact: A single Chinese DF-3A/CSS-2 IRBM or DF-4/CSS-3 ICBM with a 3.3 megaton warhead has over three times the destructive firepower in the entire Indian nuclear arsenal. In general, a thermonuclear warhead is roughly 100 times more powerful than an equivalent atomic warhead.
