Those of us who can remember all the way back to 2001 know that the original "Bush doctrine" was known as "Anything But Clinton." Basically, if Clinton had anything to do with it, it was time to scrap it. This included a lovely little agreement which had prevented North Korea, charter member of the "axis of evil," from obtaining nuclear weapons. Bush scrapped the agreement based on the idea that Clinton got tricked because the North Koreans were pursuing a parallel uranium program. Agreement scrapped, NK gets its plutonium back, makes some bombs.
And that supposed uranium program? Eh, not so much.
