Outstanding! China has the nukes but,today,Japan holds *all* the other cards.The Japanese PM need only announce that his cabinet is “reevaluating” their “open trade” agreements with China and *China* will start apologizing to *Japan*!
What makes you think that Japan does not have nuke weapons or at least the conponaents that could be quickly assembled?
We have been selling weapons grade Pu to them for decades.... And they have proven tech that could be used to deliver those potential weapons .... anywhere on Earth.

On the strength of its nuclear industry, and its stockpile of weapons-useable plutonium, Japan in some respects considers itself, and is treated by others as, as a virtual nuclear weapons state.
