Yes considerations we should never have given. This is all water under the bridge, Now What? Nuke North Korea, fallout from our weapons spreads around the world, all because NK tested one of their own nukes. I still don't see what the test will prove. Let Lil Kim jump up and down, stamp his feet, throw a Nuclear tantrum on his own country,it will be just one less nuke he has to use in the future.
I don't want NK to have any nukes, but they do and a test still will not bring about all out war.
In the case of NK, we've tried diplomacy, bribery, threats, etc., apparently to no avail with this rogue nation - the rest of the world watches to see if we indeed are just a paper tiger.
