North Korea's bellicose nuclear rhetoric has put sharply into the focus how some states are able to put world peace and security at risk and, as a result of their recent actions, this issue has moved to the top of the international agenda.
North Korean Dictator Kim Jong-Un is behaving rationally. The 30-year-old is new leader of a gang which has taken over - nay, created - an entire country, and like any boss he wants to keep his gang in power and build its wealth and status.
Nuclear weapons could foster peace and relax tensions in this region that is riddled with potential conflict. What might sound overly optimistic or even foolish has in fact a lot of arguments and evidence backing it.
