China controls China’s borders and has serious military and economic might. When it comes to things that directly effect their borders, we do what they say. China is just as interested as we are in making sure NK doesn’t manage to develop fully functional nuclear weapons, so they’re our natural ally in this situation. It’s in our own interests to play nice with China on this one, and it’s also in the interests of the desperate North Korean people, who we really don’t want to see get massacred as they try to run over the border into China.
We disagree on some major issues, but you sure do make some good points there.
