No sooner does Jack Lang, the newly appointed French envoy to North Korea, touch down in Pyongyang than all hell breaks loose. I had a feeling this would happen. Good thing President Barack Obama just decided to send his own presidential envoy, Stephen Bosworth, to North Korea to straighten things out. Here’s hoping Bosworth gets a chance to debrief with Richard Holbrooke and George Mitchell before he heads off. I’m sure those guys have useful tips on how this whole special envoy thing is done.
