Pyongyang's missile test Tuesday is evidence that North Korea is inching ever closer to its nuclear goal, warns Ambassador Stephen Bosworth.
The ambassador served as President Obama's Special Representative for North Korea from 2009 to 2011.
"I'm worried about the consequences of this for stability in northeast Asia, which is a vital region from our point of view and the point of view of the rest of the world," says Amb. Bosworth. "It puts pressure on people in Japan who believe Japan should become a nuclear weapons state. It puts pressure on South Korea for the same reason. It puts pressure on Beijing and the US."
