If NK doesn’t have nukes, China can send in troops to quash any regime-change attempts. However, since NK has nukes and if the rebels managed to get their hands on nukes and threaten to use them on China if she send in troops, China most likely can only watch while NK gets regime changed. Is that a good outcome for China?
Please look up the histories of Sino-NK relationships. Kims were never friendly toward China. The threat of NK using nukes on Beijing severely limits what China can do if NK goes rogue.
Do you think letting Vietnam to have nukes a good idea? China and Vietnam used to be “blood brothers” too.
Relationships between countries are all based on interests. How were the relationship between Vietnam and China in the 60’s? Blood brothers? How low did the relationship go after the end of the war? Do you think it is in China’s interest for Vietnam to have nukes?
NK were never that friendly toward China anyways. If the US collapses tomorrow, what will the North Korea‘ attitude be toward China given their history? Any competent Chinese leader should not take the chance of a nuclear-armed neighbour turning against China.
Again, NK isn't a Chinese vassal, and China isn't going to behave like a certain hegemony.
The relationship between China and NK isn't based on some "blood brother bond" nonsense, it's based on cold hard interests. After the fall of the Soviet Union, China is the only thing keeping the NK regime afloat, and they know it very well. As such, this relationship is nothing like the China-Vietnam relationship.
Your hypotheticals are rather irrelevant. The US isn't going to collapse tomorrow, and no NK rebels can even get their hands on a tank, never mind nukes.
It seems to me your view of NK is based more on Western propaganda than on facts and reason.
