Bush won't settle for promises. He wants to bring down the regime, and he's being advised by people who know how to do it.
Once the terms of the 'deal' become known, you'll see this for what it is. A publicity stunt to look reasonable to the leftists, South Koreans, and other Asian countries, to facilitate an iron clad multilateral case at the U.N. for sanctions later. Sanctions that will bring them down hard.
"We tried everything we could, but some people, you just can't reason with."
If you look back on how Bush handles things, you'll see that he has been doing this for years now. He keeps people off balance, uses simple misdirection, and somehow keeps winding up at the finish line first. It apparently works as well on FReepers as it does Democrats.
We will bookmark it, though, and see how it comes out. Perhaps it will be an outcome based on the combine predictions and insights of the both of us..... :-)
