Saudi Arabia isn't even in your top 20? Or North Korea?

Indonesia more influential than nuclear, mega-populous Pakistan? And Iran and Israel?

I tend to weight economic power more.  Nuclear weapons are a deterrent but since in de facto terms they are not usable as an offensive weapon I tend to weight them less in terms of power.
