If we had a president with some guts, he’d offer all the steak they can eat to the North Korean army if they turn on the dictatorship. But no, Obama is too busy eating wagyu beef at cocktail parties to ever entertain something like that.
This has already been done and it didn't work. The US, South Korea and China give the North food in exchange for non-compliance on most issues. GHB, GWB, Clinton and most likely Obama will play this game. Every third world nation that wants the bomb is playing this game and the US is losing. Our leaders can't seem to figure out how the world has worked in the last twenty years.
