The only major neighbor China makes nice to is Russia, which is also the only neighbor with enough nuclear weapons and ballistic missiles to cripple China. The lesson is not lost on the rest of China's nervous neighbors.
For all the Leftists who argue that North Korea and Iran can't be blamed for wanting nukes because we supposedly would invade them if they don't have nukes, how will they react when China's neighbors go nuclear out of fear of China?
That was a rhetorical question, of course.
