Well, blaming is all you're good for. So you must be having fun spreading blame around.
Now, where is the quote in which President Bush PROMISED that NK would not be allowed to get a nuclear weapon? There isn't one. He has not PROMISED that the Korean Peninsula would never have a nuke on it's soil. What he HAS repeatedly urged on the world is that a nuclearized KP would be unacceptable and extremely dangerous.
It is Iran that he has said "will not be allowed to have nuclear weapons". You are confusing the two.
He keeps repeating that President Bush "PROMISED," but has yet to offer any evidence other than his own claim.
silent......if you want to be a good little Bush basher, you have to have your documented evidence at the ready. Otherwise no one will take you seriously.......
