Top 20 Great Powers

Why Germany above UK? Brits have some fighting experience in last years at least.
Unlike China India has quite up to date imported equipment while China mostly rely on self produced copies of old soviet craft. Eventhough indians are well known for their unability to properly use compliceted equips, India would surely has some advantage in short convenient war.
Russia has army only of 500-550k men, at least half of this number are useless in real warfare conscipts. Overall Russia can deploy only 50-70 thousands soldiers on battlefield, other personnel do not really fit modern standards.

Well polish horsemen were quite formidable force

China already destroyed India in a war once in the 70s. A country with the same population but an IQ average of around 15 points lower can't beat China.

Did you just say Germans are nationalistic?

You can take German out of a Nazi, but you can't take Nazi out of a German.

You may be overrating Argentina a bit too and I don't see how Poland/Netherlands/Sweden are above South Korea, but nice list anyway.

Europeans. 'Nuff said.

UK and France should follow USA/China/Russia. Being on the permanent council of the UN is a diplomatic bonus, plus nuclear weapons.

A good way to see who is and who is not a great power is to see who is invited to the great conferences regarding something. Like, Russia and the US were invited to the Berlin conference regarding dividing Africa even though they didn't want any African colonies. But they gave an opinion.

The same can be seem today in the issue of Iran's nuclear capabilities. The group that decides that is P5+1 (five security council members plus Germany). When the issue is North Korea, the group is Russia, China, Japan and the USA.

So my ranking (I'd include Nobel laureates in hard sciences as a measure of prestige and how scientifically good the country is) would be

1. USA
2. China
3. Russia
4. United Kingdom
5. France
6. India
7. Japan
8. Germany
9. Italy
10. Brazil
11. South Korea
12. Canada
13. Turkey
14. Israel
15. Spain
16. Saudi Arabia
17. Iran
18. Mexico
19. Taiwan
20. Australia
