I would bet that if North Korea really wanted of the terrorist list that they would be a happy to do what it takes in order for that to happen. Would NK be able to do it if we increased the incentive by saying that we could "loan" them some money at a "low  and generous" rate with the intention that they build factories so the can make some money for themselves and for their people. They say if you give a man a fish you feed him for a day but if you teach him to fish you can feed him for a lifetime. I would like to say that the longer it takes to finish the disarmament of NK's nuclear facilities the less likely we are to be generous with what we have to offer. The longer it takes is an example of how future things will take place and means that we take the NK's word at an even lesser value as time progresses. They need to act soon and it would be best if they could do it now... or even better if they have already done it.
