Describe the US-North Korea relations and the role of China in resolving the disputes.
The dude just blinked.  China was told by Trump to stop him or trade will dry up with us.  China listened.  Trump's pushing back on him is what did it.  He still will have to be taken out.  
Trump is brilliant.  He used China to do his dirty work for him, and is getting a good trade deal with China, is shutting up the little pork sandwich man, and just averted war for now.  All because he used his 170 IQ and went around the whiners and complainers.  Way to go Trump!!
#MAGA!!!
