I'd go so far as to say it doesn't even matter so much if it's democratic. It just needs to be a government that sees itself as responsible for its people and that has a stake in the global community. The danger of "rogue states" is in their seperation from world affairs.
What we need to think about is supporting other paths for nations to really get into the loop and gain influence. The status quo is that getting a nuke is the best way for a rogue state to assert itself. Under the status quo, it is foolish for them not to.
