Anyone feeling sorry for the Chinese yet? NK with its nukes is a bigger problem for the Chinese than USA.
It is a master stroke by the USA to let NK develop and announce its nuclear capabilities. This will keep Chinese looking over its shoulder wondering what its unpredictable neighbour is going to do.
The concept of NK being a threat to China is laughable. NK is so bankrupt that China supplies it with life sustaining goods including food. NK is a China proxy, pumped up by China to torment its old Asian foe Japan, just as it as played Pakistan against India in South Asia.
