a war with the Japanese may be sharp, but isn’t going to be short>>>>>>>>>>>>>>>>>>>>>>
Its very likely that Japan has nuclear weapons, although they are “untested” outside of computer modeling.There have been rumors for years.
I doubt that China or the NORKies would want a sizeable portion of their coasts glowing in the dark.
I suggest that Japan will test a nuke very soon if things do not cool off very quickly. They need to remove all doubt in the PRC’s game plan as to what Japan’s strategic capability entails. Being coy like the Israeli’s won’t work in this situation.
Japan not only likely has nuclear weapons, they’re probably like all things Japanese, very precisely made and they’ll work. They’re the Lexus of nukes.
Despite their vast armies and huge arsenals, the Chinese are still bass-akwards; there is a sound basis for the phrase “Chinese Fire Drill.”
The Japanese, meanwhile, are sharp as a tack, and venomous, unrelenting enemies.
The North Koreans, if they got dragged into it, would probably stop at Seoul. I suspect, although I couldn’t prove it, that the North Korean rank and file would surrender pretty quickly once they arrived in the southern region of abundant kimchi and barbecue beef. Maybe significant numbers of officers, too.
