I don’t agree that we should do whatever China tells us to do. That’s not the America I know and love.
The North Korean population won’t be swarming over any borders. They’ll be shot if they try. Those shots were not China’s call though. Obama’s pen pal gave that order.
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.
