Why all the talk about negotiating with North Korea, about failed diplomacy and the like. You can't negotiate with someone who is never willing to settle or compromise. Negotiaions with the North without a credible threat to the power of the dictator is simply volunteering for extortion. North Korea will not come to the table unless you pay them, will not stay at the table unless you pay them and will break any "deal" they enter regardless of whether you pay them. Why would they do otherwise? There is no downside for the dictator and the world will blame America.
