North Korea's bold acknowledgement that they have violated the 1994 treaty, even after taking billions of dollars in aid (or bribes, depending on how you view it), has many nations worried. North Korea has been shameless,  aggressive and successful in it's extortion efforts. But it is believed that the North Koreans already have one or two crude, but working, nuclear weapons. While untested, these weapons give the North Koreans new opportunities to extort aid from their neighbors and Western nations. There are apparently a number of senior North Korean officials who have noted that these extortion efforts have been successful and now want to squeeze a little more. How do you say no to an extortionist with a nuclear weapon? At the moment, North Korea's usual victims don't have an answer.
