I do not believe there will be any violence.
China’s #1 problem is 25 million people need to enter the workforce each year in order to forestall a full civil war in China. The population is fractious as seen by the fact that there are four different HDTV broadcast protocols with no interoperability.
China has said openly that if the USA increases tariffs or engages in a boycott of Chinese goods, they will consider that a declaration of war and will launch a full nuke attack on the USA.
Trump basically told the President of China that if China takes out Fat Kimmy, Trump will back off of pressing China for trade concessions.
I think China will tell Fat Kimmy and the military leaders that they have been annexed by China. Done deal. Resistance means death to millions of NORK’s.
China will dismantle the nuke program and unload the tubes facing Seoul. China doesn’t want our THAAD anti-missile system in South Korea, so they will simply remove the threat of rockets and missiles.
Fat Kimmy will live in exile until he is executed by Chinese agents. All relatives of the Kim Dynasty will be killed.
The DPRK will simply become a province of China. BTW, I think Wall Street agrees with this scenario.
May be something to what you say.
