North Korea
I've been wondering for a while why the North Korean government wants to deal straight with the U.S. instead of it's neighbors. Powell sums it up nicely in the quote below.

"The North Koreans desperately want to make this a U.S.-North Korean problem to see what else they can ask us for, to pay them, to reward them for their misbehavior," he said. "And we have chosen not to do that, not to get caught in their trap again." usinfo.state.gov

So, it boils down to money. Kim Jong-il wants a pay-off. He wants the U. S. taxpayer to prop his oppressive government up because it cannot possibly maintain a successful economy.
