As an aside, a friend of mine just posted a tongue-in-cheek solution to solve the "North Korea" problem:
How much to buy North Korea?
What is it worth to the US and the free world to rid ourselves of this half-pint half-assed dictator? It is not worth one American casualty, but it is worth something. I'm thinking $1,000,000,000,000. Yes, One Trillion Dollars. We should be able to buy off every DPRK ***** of any significance for that amount. Every military officer. Every Communist party official. Every "Businessman". All of them.
We can split it between the US, Japan, S. Korea, and the EU. $250B each, payable in equal installments over 20 years. That is $12.5B each per year. Done.
Terms: Surrender Lil Kim and your nukes. Get paid.
Free passage to any country. Full pardon.
Make the offer good for 1 year. Then sit back and watch.
Either the regime takes us up on the offer (WIN) or they implode fighting over it internally (Win).
I love win-win scenarios.
