**UPDATE** North Korea is giving the US, PRC and UN the finger with missile launch. Here's the piece. It is not inaccurate. The President has postured, moved assets, and made a big deal of it. Un thinks the President is bluffing. You can't bluff at this level - if you do, you lose. If the President does not militarily hit NK (which could include an assassination of Un), his credibility is done.
He painted himself into this corner. Perhaps he did it intentionally, perhaps not. Either way, if he chooses to fall back on 'diplomacy' and 'sanctions' at this point, he writes the death warrants for all US servicemen on the South Korea side of the line.

Story is just breaking, very few details as yet.
