Not logical for China to tolerate threat of nuclear conflagration on iPhone's logistic chain

An analysis of the components of an iPhone assembled in China shows 34% from Japan, 13% from South Korea and 25% from various others ranging from Mongolia to Malaysia. The point is that its a logistics chain on which China is very dependent for economic growth. A growth that is an essential part of fulfilling the leadership's bargain with its people.  It's logical that the leadership builds up a military to protect this valuable economic engine. What is not logical is its tolerance for the Kid Playing with Nuclear Match Sticks threatening the neighborhood with a conflagration that would be an incalculable set back for the region.
