Locally, this young lady was recently suspended for violating the dress code. This was during a "spirit week" where students could bring a dollar to donate to Red Cross and in return dress up as a daily "theme".
She was dress coded because her outfit was "too revealing". This is a public photo that appeared in the local newspaper.
That is an opinion piece and while it is well written by an "expert" I could refute with an equally well written opposition opinion written by an "expert". In the end they are just opinions. You hold to one, I hold to the other. Fair enough.
China wants two things: Stability along it's southern border and a reduction of US military forces on the Korean peninsula. NK developing into a full nuclear power does not further either of those goals.
Trump gets a lot of crap for his infantile tweets, but NK is really the escalator here. They are literally defying the entire international community and continue to fire off test ICBM's like it is their own personal firework display.
I don't know what is going to happen, but any armed conflict will have to occur before NK develops reliable nuclear weapons. China will allow conventional intervention despite having a mutual defense treaty, especially since NK is ignoring China's calls to back off, but there is no way China would allow any sort of nuclear conflict to arise without retaliation. Once NK has reliable nuclear weapons and the ability to deliver those warheads the option for a conventional armed conflict basically disappears.
