Nutshell..
North Korea is a backwards country that cannot make it on their own with that half-wit midget dictator with the bad hair cut.
Starting in the 1990s, the midget figured out that he could get stuff from us (food, money) by threatening to build nukes.
Clinton bought it hook line and sinker..gave them "stuff" and hoped it would go away. It did'nt. They kept on working toward Nukes secretly.
Forward to 2000. Bush elected. Names N. Korea as part of "axis of evil" after figuring out that the midget had played Clinton like a violin. The midget does not appreciate this and plays the NUKE card again..looking for more "stuff".
2001-2. We invade Afganistan, then Iraq. "Gene pool reject guy" determines NOW is a good time to pressure us for "stuff" because we are tied up militarily. He demands two way talks. Bush, knowing FULL WELL that China has THE only leverage with this mental and physical midget refuses. Dems go wild (remember?).
2003 and patience has paid off as 6 way talks begin. It is clear, again, that blackmail is bad haicut boys plan. Dems are silent....Oh and BTW, now that the midget KNOWS we are not screwing around, part of the "STUFF" he wants from us is assurance that we will not kick his ass. Which is a better bargining chip to have at the table...
2004 Mini-me getting stressed that we have not caved on 2-way talks. And militarily we are getting closer to..freeing up some muscle. Now says he will agree with 6 way talks only after election...hoping for a democrat like Clinton to be elected. Kerry (re)proposes BACKWARD step of 2 way talks saying "China wants it". (P.S. OF COURSE China wants the US in two way talks...its OUR money N. Korea wants after all and anything that weakens us or makes us pay is, well, not a bad deal for China

. Meanwhile, Bush is applying pressure behind the sceens to make China apply pressure behind the sceens on the midget. Clear?
Thats it...not a real threat in the classic sense, just a high stakes game of blackmail.
