China already has 4 nuclear armed neighbours plus potentially three more viz Japan, Soko and Vietnam.
Supplying nukes to Pakistan will be avenged by India at a time and place of its choosing.
Easy man!
Also, Vietnam ain't gonna have any nukes.
Why?
Because China will then enter Vietnam to rid them of WMDs as US entered Iraq.
According to Chinese law, a presence of a nuclear weapons program on Taiwan will be grounds for immediate attack on Taiwan.
To be honest, you have really overestimated your technological capability.
Just look at Shinshin, this is the best you can do.
Not really.
Japan has all the technological capacity to do that. Actually, nuclear weapons are a really old 1960s technology, but most states don't do it for a variety of reasons.
Japan is nearer to a nuke, than Iran is to one.
Japan can test thermonuclear weapons within 9 months, if its scientists get the go ahead.
India must not hesitate to help or assist Japan.
We do not have any reason to refrain ourselves from helping Japan, India's 'friend'.
As far as Indo-Japan relations are concerned we shouldn't be thinking too much of consequences because 'Indo-Japan closeness' is already a consequence.
Japan of today, that is 2015, if more technologically capable of the India of 2020.
So that said, Japan needs no assistance if it were to ever decide to tread this path.
Japan right now is in US nuclear umbrella, and US is determined to have Japan as an ally right now. If the US alliance were to ever falter, Japan can develop 1000 thermonuclear nukes within 2 years.
It already has the weapons grade plutonium.
China can send something
1000 times brighter than the sun to you.
At 0:48 , we can see how small the sun is .
1967, weapon sized H-bomb, yield 157 times of Nagasaki "fat man"
No need to invoke Nagasaki here, especially when talking to a Japanese member here.
