Sounds like China would bomb North Korea before we would. And they wouldn’t be pay attention to rules or international law if they do it.
Via Daily Caller:
If North Korea crosses Beijing’s “bottom line,” China may bomb its neighbor.
China warns the North’s nuclear activities must not jeopardize northeastern China. If North Korea negatively impacts China with its illicit nuclear activities, the latter will respond with force, a Global Times editorial published on the news service for the Chinese military stressed.
“China has a bottom line that it will protect at all costs, that is, the security and stability of northeast China,” the report stated. “If the bottom line is touched, China will employ all means available including the military means to strike back … By that time, it is not an issue of discussion whether China acquiesces in the US’ blows, but the Chinese People’s Liberation Army (PLA) will launch attacks [on] DPRK nuclear facilities on its own.”
