Officially, the US has around 5,550 nuclear warheads. The US has a population of around 333 million. Per-capita, one American nuke is equivalent to 60,000 Americans.If the US wants to negotiate nukes, just open with this:
"Just let us know the number of nuclear weapons per capita you would like for both of us and we will accept."
Doesn't even need to be a meeting, just an email.
The current best guesstimate of China's nuclear stockpile by Pentagon is around 400 nuclear warheads. China has a population of around 1.411 billion. Per-capita, one Chinese nuke is equivalent to 3.528 million Chinese.
To-be-frank, I am always a firm believer that China should have a military power that is scaled according to the size of her population. Therefore, if China were to use the same nuke-to-citizen ratio as the US, that would be 1,411,000,000/60,000 = 23,500+ nuclear warheads.
That means China should have 23 thousand nuclear warheads at minimum.
Take that, DC! (lol)
