C'mon AIT you of all FReepers should know this is just Kabuki theatre.
Rather, it is a violation of UN Sanctions and Resolutions and defies good faith. It also violates the Panmunjong Accord of last year signed by North and South.
It is/was also predictable, only because they have done this as far back as we have had a relationship with them. We don't have to underreact or overreact, but it should be accepted that the limits of diplomacy with such a regime may well be approaching the final stages before obsolescence and irrelevance--and we shouldn't try to beat a dead horse. We never dismissed any such provocation like yesterday, ever, (to my 21 year recollection) here on FR during any time during the Clinton or Obama regimes. We are just being consistent. They are who they are regardless which Administration we have in power.
