I expect we'll be getting (at least) another very strong hint that Japan has nukes that are all but assembled. They've already got the requisite missile capability. China
... but I don't know what China's response has been.
I think it will depend on Japan's response. NK is nothing to them, but a nuclear Japan probably scares them to death.
Japan can build nukes at a drop of the hat, but then Taiwan and S. Korea will want them too. S. Korea can do it probably now. Taiwan could if they wanted. China will wig out about that of course. We need to stop N. Korea before it gets out of control. They have had 50 years to get rid of this thug and his dad, they might need to be collateral damage. Stone age em.
A new kind of Cold War is back. On top of the WOT, this isn't good.
