I think it's only a matter of time before the u.s start arming s.k and Japan with nukes. China should prepare for such eventualities
the day Japan and Sk got nukes should be the day Iran has nukes as well
I think that's how China should respond
Yeah, and China will just watch without doing anything? Ofcourse not. China will Bomb Japan before it ever gets nuke. Look at Israels playbook of Bombing Iraq and Syrian Nuclear plants. China will absolutely not allow Japan to have Nukes.
As for South Korea, Its too close to Beijing to have Nukes as well. I think China will put enormous military pressure on South Korea to give up.
