Not in total disagreement with you but I wonder what basic criteria YOU use to distinguish a country as a "Super Power". I know that nuclear capability is one I would agree with. Perhaps the ability to project substantial and significant force world-wide would count. Not sure about population size or density.
For that reason, perhaps a sub-category might be appropriate:
Super Power
- USA
- Perhaps China
Power
- EU can certainly defend their portion of the continent but really can't sustain a force projection mission that is truly meaningful.
- Russia was there but still has not recovered all it's capabilities.
- India and Pakistan can nuke each other and a few surrounding countries but would never be a real threat to the USA or China.
